INTRODUCTION
This flexible, yet powerful, series of digital strain gage transducer indicators were developed from a
family of precision pressure calibrators. It is the ideal solution for meeting the measurement and display
requirements of industrial applications.
The standard product may be made even more powerful through the selection of options to detect
preset alarm points, sense speed, calculate work (HP), and provide a digitally derived analog signal to
communicate with other devices.

PEAK/ TRACK HOLD (MIN/MAX) FEATURE
General:
The Min and Max mode is designed to capture and store the highest and the lowest torque readings in
the unipolar or bipolar modes . These values may be recalled at any time in the normal operating mode
by repeatedly pressing the DISPLAY key until the desired value is displayed. When either the MIN or
the MAX value is selected the alphanumeric display will flash between the mode (MIN or MAX) and
its units.
Note - The MAX and MIN torque data is automatically converted to any of the active conversion units
by stepping through the conversion units using the UP or DOWN arrow keys.
The MAX and MIN data is stored in non-volatile memory and therefore will not be lost when
power is removed from the meter.
Both the MINIMUM and MAXIMUM mode are independent of each other and are enabled
(turned ON) in the CONFIGURATION mode. These are off by default and MUST be turned on to
see any of the following displays.

This function sets the length of the register that controls the moving average which is a first in first out
(FIFO) type of filtering scheme. For example: Since there are 20 conversions per second, a filter value
of 5 will average .25 seconds of data; and every .05 seconds the oldest value scrolls off the register.
The higher the filter number, the more registers used, thereby smoothing the displayed value more.

The allowable range (in percentage of absolute full scale) that the user can zero the display. This value
refers to the absolute value. For instance, if you set the value to 1% and the next day observed that
value had shifted to 0.75, if the zero key is pressed the value on the display will zero out. The next day
you observe that the value on the display is 0.5. The meter will not zero out because the system has

This completes the calibration setup mode. Open switch 2 on dip switch S1 to return to the normal
operating mode.
Linearization
The ideal calibration curve for a meter is a straight line, as shown below. However, in reality the best
we can do is get near this linear fit. By using the linearity feature, you can create a data set of known
values. After this base curve is set up, the next data points can be interpolated from a line segment of
the data.
The 7550 instrument linearization feature is enabled for up to 10 calibration points (SPAN 1 – 10 CAL
TARGET) which are sequentially entered. If using Shunt Calibration setup, only the first span point is
utilized. For the linearization feature, you must perform point by point linearization through deadweight
loading each span point. If a calibration is performed with less than ten (10) points, the curve will be
extrapolated to full capacity based upon the slope correction between the last two (2) entered SPAN
CAL points. In the example below, if only four (4) span calibration points were entered (SPAN 1 to
SPAN 4), the slope correction from SPAN 4 to full capacity would be defined by the computed slope
between SPAN 3 & SPAN 4. During a calibration, if fewer than ten (10) SPAN CAL points are
desired, simply step past the remaining calibration points using the

Resetting Span Calibration Points:
To reset the span calibration points step to the desired SPAN CAL point using the

then press the

If you select yes, the correction factor of the selected SPAN CAL point and all others beyond will
be reset to unity.
Important ! - If all ten (10) SPAN CAL points are not used in the calibration, the last span calibration
point to appear is not an entered correction point. It only indicates the next span calibration that can be
entered. It is essentially ‘skipped over’ when you press the NO
key to advance.
Overwriting Span Calibration Points:
Any SPAN CAL point can be overwritten with a new value provided that it remains within the range
bounded by the span calibration points above and below the span point to be overwritten. The
illustration below shows SPAN 2 CAL point being redefined within the boundaries set by SPAN 1 and
SPAN 3. To overwrite a span calibration point, step to the desired point using the

DIGITAL IN
Introduction:
The 7550 meter has two channels for digital input and output. Digital input and output can be
accomplished by setting jumpers S4 and S5 and connecting a few leads.
The following is a diagram of the basic hardware for the Digital input and output:
Figure 5-1, Digital In
51
Section 5.2
FREEZE MODE AND DIGITAL INPUT:
One example of digital input for this meter is freeze mode. This mode, often used for testing pressure
switches, is an edge triggered input signal that will “freeze” the last display update for the number of
seconds (1 to 10 seconds) selected in the CONFIGURATION mode. The FREEZE mode is enabled
in the “CONFIG ?” menu under Freeze time selections. Instructions for enabling freeze mode are
included later in this section.
Either opening or closing of a switch contact between an active input (I/O 1 or I/O 2) and RETURN
will “freeze” the display for the selected amount of time (in seconds), as shown above. However, while
the display is in the freeze condition it will not respond to another contact transition.
The following is a diagram of the meter set for digital input. Note that the jumper positions would be the
same for any other application of digital input. The two leads of the hardware must also connect to the
I/O positions, but the device attached would not have to be a switch.
Figure 5-2, Freeze Mode
Freeze Mode Specifications:
The Freeze input will “freeze” the display for approximately five seconds on the rise and fall time of the
input (edge not level triggered) and is “non-retriggerable.”
Input pulse > 100 ms required to guarantee detection.
The freeze will “freeze” the 6 digit numeric and LED bar displays in whatever mode it is in (i.e. Normal,
“net”, Max, or Min mode).
Alphanumeric display will prompt “FREEZE.”
52
During the “Freeze” the Front Panel Keys are inactive.
Inputs are a +5vdc logic level. Sinking current ≈ 0.5mA.
Enabling Freeze Mode:
1. To enable freeze mode, you first need to enter the configuration mode. You can do this by closing
DIP switch 1.
2. Press
to step down through the menu steps or
until the display says “CONFIG?”. Then select

to go to the previous menu step
to enter the configuration mode.
4. Press
or
to turn Freeze mode off or to set it to 1-10 seconds.
5. The CONFIGURATION mode may be exited at any time by pressing the 'CE' key. If the CE key
is pressed, a confirmation prompt will scroll continuously until the YES or NO key is pressed. Be
sure to open switch 1 to get back to normal operating mode.
53
Section 5.3
DIGITAL OUTPUT:
This meter can also be set up for digital output to take advantage of various TTL devices. The following
is a diagram of the correct jumper position for digital output. Note that your device must still connect to
the I/O positions on the board.

Section 6.1
SERIAL DATA OVERVIEW
General:
The 7550 offers easy access and configuration of two (2) serial communication ports, PORT 1 and
PORT 2. Both com ports are ASCII - compatible and thus the serial data output formats are
compatible with most printers, scoreboards, or other remote serial devices. Port 1 may be configured
for bi-directional, Full Duplex, or Half Duplex (duplex = two way communication) mode of operation
while Port 2 is restricted to a Simplex output mode only (simplex = one way communication). The two
(2) communication ports support both RS232 and 20 mA current loop (passive or active). In addition,
Port 1 also supports RS485, or RS422 communication.
The transmission of serial output data strings can be initiated in one of three (3) ways:
1. on demand output
2. continuous output
3. by serially soliciting the indicator in a duplex (bi-directional) mode of communication.
55
Section 6.2
SETTING UP THE SERIAL PORT CONNECTION
Port Modes:
The ports can operate in the following modes:
Port 1 (set up selections)
OFF
Turns Port 1 Off.
PRINTER On demand printout of the data when the PRINT key is pressed or the
Remote Print input is issued. The Printer mode is a simplex output mode.
DUPLEX Bi-directional communication in which serial data can be both received and
transmitted between the indicator and a remote device such as a computer.
SIMPLEX Continuous serial transmission.
Port 2 (set up selections) - No DUPLEX communication
OFF
Turns Port 2 Off.
PRINTER Same as Port 1.
SIMPLEX Same as Port 1.
Printer (Port 1 or Port 2)
The selection of the PRINTER format is an on demand serial data transmission that is initiated each
time the Front Panel Print
key is pressed or when a Remote Print input is issued. This mode of
serial data output is used when interfacing to printers. The PRINTER mode of communication is a
simplex serial output. However, for this to work, “Port 1 PTR” must be set to ON. Please refer to the
part of section 6.2 entitled “Establishing Communication.”
Front Panel Print
key INPUTS 1 and/or 2 can be configured to initiate a print
command (Refer to section 5.1, entitled ‘Digital In’).
The following is a diagram illustrating how the print option can be used:
56
Figure 6-1, Printer
Establishing a Connection
Note: The following steps will help to set up a connection to a standard device such as a computer
serial port. There are many different ways to configure the meter to communicate, but these
settings should act as a basic guide.
1. Use a cable to connect the 25pin port on the back of the meter to the 9pin serial port on your
computer. We used a DB9 Female to DB25 Male Modem Cable, but a similar cable should also
work.
2. Close dip switch 1, as explained in section 4.1. Press the NO
screen. Then press the YES
key until “I/O ?” is on the
key.
3. “Port 1?” should now be displayed. Again, press the YES
key.
4. The first item to come up is “Port 1.” This should be set to Duplex. Press the NO
advance. Use the left and right arrow keys to change this value and the following ones.
5. Press the NO
key until “Baud” is displayed. Change the setting to 9600.
6. Press the NO
key until “Parity” is displayed. The setting should be None .
7. Again, Press the NO
Modify.
key to
key. “Port 1” should be displayed. This item should be set to
8. Press the NO
key until “Port 1 PTR” is displayed. Change the setting to On. This step is
not mandatory, but if you want the meter to be able to send the reading to the computer with the
PRINT
key, this needs to be enabled.
57
9. Again, press the NO
key until “Port 1 Cont” is displayed. The recommended setting is
Off. If it is enabled, the data will continuously send the reading to the computer screen.
10. Press the NO
key until “Resp” is displayed. Change the setting to Echo. This setting will
allow your commands to be displayed on the computer screen.
11. Finally, press the NO

key until “Exit ?” is displayed. Press the YES
key and then
The meter is now set up and connected, but you must now open up a program which will display the
information. Any terminal emulation program such as Hyperterminal should be able to display the data.
Be sure to choose the correct com port which corresponds to the serial port and to have the port on or
open. Finally, ensure that the terminal is set to echo the typed text so that you can see the commands
you are typing.
If one terminal program is not working well, try a different one.

Section 6.3
DATA FORMATS
ASCII - Data Formats:
Each serial character sent out in the serial data string is in ASCII - compatible format. The data format
selection is based on Parity selection in the I/O SET UP mode (Refer to Section 6.2 for configuration of
Serial Ports). The data format for each ASCII character is of the general form described below.
One ASCII character consists of:
(1) Start Bit,
(7) or (8) Data Bits (data bits are the bits that actually encode for the ASCII character)
(1) or No Parity Bit
(1) Stop Bit
ASCII - Data Formats Overview:
The table below summarizes the different Data formats available through Parity selection.

SERIAL OUTPUT WIRING And HARDWARE
CONFIGURATION:
This section details the wiring configuration for serial transmission to a Remote Device such as a Printer.
All direct wiring on Terminal Block (TB3) and hardware settings are well marked and can be located at
the rear portion of the CPU board assembly.
The 7550 Panel mount indicators come equipped with a twenty five (25) pin “D” female serial I/O
connector mounted at the rear of the enclosure which provides access to Port 1 RS232 or RS485 hook
up.

DUPLEX SERIAL PROTOCOL
General:
The duplex protocol includes the following basic functions:
1. Special commands for filling.
2. Setup entry and recall.
3. Current pressure data recall.
4. Calibration and correction recall and entry.
5. All front panel key functions.
6. Temperature calibration and correction recall and entry.
7. The protocol between the "standard" full duplex and the RS485 will only differ by the addition of the origin and
destination address characters.
8. The protocol will be designed to be expandable for future growth and special applications.
Full Duplex Protocol:
Communications from the host computer into the 7550:
*<DD><OO><cmd><{><data entry><}><CHECK><CR>
Response from the 7550:
:<OO><DD><cmd r><{><data resp><}><CHECK><CR>

Three character command echoed from 7550.
Start of data character (7BH).
End of data character (7DH).
'{' and '}' only sent if data entry or recall.
Data entered into 7550 if entry command.

Optional two character check if selected.
= Message terminator (0DH).
A "LF" character following the "CR" will be ignored. All characters following the "CR" and
preceding the "*" will be ignored.
Note 1: The asterisk (*) is what tells the meter it needs to respond to the command. ALWAYS begin with the *.
66
Note 2: The colon ( : ) indicates a response from the meter. However, the response :NAK means that the
command was not correct and :NAC means that the syntax was correct, but the command could not be
completed.
Note 3: For most of the commands, you do not need to enter the DD or OO items. Instead, you may just start
with the command itself.
Example: *CPE{001000}
will set the capacity to 1000. Notice that most of the items from the top description have been omitted.
Note 4: Many of the setup and configuration commands must be done with dipswitch 1 closed.
Command Code <Cmd> Description:
The <cmd> consists of three (3) characters "ppt" where:
pp
t
= the command parameter
= the command type
The three (3) command types (t) are as follows:
1. Direct cmd code = < D > character (44H).
‘D’ Commands have no data associated with them.
Examples:
General commands (Zero, Tare, etc.)
Display commands (Min,Max, etc.)
Weight calibration (Zero Cal, etc.)
2. Data request code = < R > character (3FH)
‘R’ Commands requesting data from the host to the 7550.
Examples:
Torque data
Status
Setup data
Calibration data
3. Data entry code = < E > character (45H).
‘E’ Commands with data sent from the host to be entered into the 7550.
Examples:
Setup data
Calibration data
Note 1:
For complete listing of command codes see Table 6-15.
Note 2:
The D, R, or E letters are already included within the 3 letter commands. Do not add it at the end as a
fourth character.
Data Format:
When data is transmitted it is always bracketed with the '{' and '}' characters.
The separation character '|' (7CH) is used to separate data in a string.
All 7550 recalled data has leading zero suppression with the zeros transmitted as “spaces”.
All data entered into the 7550 can have leading zero suppression with the zeros transmitted as “spaces” but
is not required.
67
68
Section 6.8
RESPONSE
In the print/port 1/duplex setup the response by the 7550 from the direct commands and data entry commands can
be selected for 'None' or Echo'. This was briefly covered in step 10 of ‘Establishing a Connection’ in section 6.2.
The following is a brief description of each command:
'None ': no response is given a direct cmd (D) or data entry cmd (E) if valid or invalid.
'Echo': the command (direct or entry) is echoed as received if valid; the start of transmission character is
returned with a ':' not the '*' character. If invalid a ‘NAK’ is returned
'Ack/Nak': instead of echoing back the received command code and entered data the 7550 responds with
'ACK' (41H, 43H & 48H) in place of the code. If an error in received data is detected the 7550
responds with 'NAK'(4EH, 41H & 48H).
Ack response: :ACK<CR>
Nak response: :NAK<CR>
An invalid input consists of the following:
1. Parity error.
2. Check error if enabled.
3. Invalid command code.
4. Invalid data format.
Response in Echo or Ack/Nak mode = :NAK<CR>
Commands Received As Valid But That Can Not Be Performed
A valid command in the Echo or Ack/Nak mode that can not be performed will respond with:
:NAC<CR>
The conditions that give you a ‘NAC’ response are:
Not in a valid mode for the command. For example, a ‘Cal’ command in the ‘normal (run)’ mode (Refer
to Command Performance Status Table Below).
2. The Command is acting on a parameter that is disabled in Configuration. For example, Peak data recall
command when the Peak is configured for ‘off’. (Refer to Command Performance Status Table below).
3. The command is acting on a parameter that can not be performed due to the unit conditions such as
motion or over range.
1.
The following table shows which commands can be used in which modes. Refer to section 4.1 to see which
jumper positions correspond to each operating mode. In general, most of the commands can be performed
without any dipswitches closed or with dipswitch 1 closed.

CHECK OPTION and RS485:
Check Option
The check option is available under the I/O menu under Port 1. The check option is set up in the print duplex
mode of port 1. It can be applied to the duplex serial in the RS485 mode or in non addressable mode.
If check setup is set for 'NONE’ (OFF), no characters are transmitted for check.
Checksum: if checksum is selected the check consists of two ASCII characters.
1. All ASCII characters including the starting character and terminating character preceding the checksum
are included in the checksum.
2. The ASCII characters are binary summed (not including the parity bit).
3. The least significant byte is divided into four bits each "nibbles" and 30H is added to each. Therefore a
sum of 5EH will be transmitted as 35H and 3EH or '5>'.
Xor: if exclusive or is selected the check consists of two ASCII characters.
1. All ASCII characters preceding the checksum are exclusively or'ed together.
2. The check byte is then calculated to give a result of zero when it is exclusively or'ed in.
3. The check byte is divided into four bits each and 30H is added to each.
RS485
The RS485 protocol is the same as the standard duplex except the two character destination address and two
character origin address are included after the starting character.
The host computer's address is fixed at '00' and the 7550 address can be set between 1 and 98.
When the setup is not set for the RS485 mode the RS485 transceiver is set for transmit only (RS422 applications).

Section 6.11
CAPACITY/RESOLUTION ENTRY, BASE UNITS ENTRY, AND
RECALL
Two important commands for the calibration are the capacity and resolution. The capacity must be set in order to
properly calibrate the 7550 and the resolution, or count by setting, must also be appropriately set. The following is
a summary of the commands needed to enter these settings.
COMMANDS:
CPE{} / CPR = Capacity.
REE{} / RER = Resolution.
The CPE{} command is used to enter the capacity and the CPR command will recall the current capacity.
DATA FORMAT: <data>
LENGTH:
Fixed at 6 characters.
WHERE:
data: Six (6) character data field with no polarity and decimal point.
-Entry with or without leading zero blanking.
-Recall with leading zero blanking.
EXAMPLE:
*CPE{001000}
This will set the capacity to 1000 in the default units.
The REE{} command is used to enter the resolution and the RER command will recall the current resolution.
DATA FORMAT: <data>
LENGTH:
Fixed at 5 characters.
WHERE:
data: Five (5) character data field including decimal point when required.
-On Entry and Recall, if a decimal point is included then use full leading zeros; if no decimal point is
included then begin data with a space followed by leading zeros.
EXAMPLES:
*REE{ 0001}
This will set the resolution to count by ones. Note the space before the first zero.
*REE{0.001}
This will set the resolution to count by thousandths.
Base Units Entry And Recall
The base units command is used to set the default value for the units. The following is a description of the
command.
COMMANDS:
UUE{}/UUR = Base Units Entry And Recall
The UUE{} command is used to enter the base units and the UUR command will recall the current base units.
FORMAT: <unit1>
LENGTH: Fixed at one (1) character.
75
WHERE:
unit1 : see Table 6-3 (example: A=lb ft, etc.)
EXAMPLE:
*UUE{B}
This will set the base units to lb-in, as shown in Table 6-3.
76
Section 6.12
CALIBRATION:
General:
The calibration feature is one of the most important procedures for the unit. Because of this, there are commands
which specifically help to go through the calibration procedure. The following is a summary of these commands:
Note:
The unit must be set for Calibration (dipswitch 1 or 2 closed) for these commands to work.
COMMANDS:
ZCD
LRD
RxD
LxE{}
ZFE{} / ZFR
LXE{} / LXR
LFE{} / LFR
LCE{} / LCR
HCE{}
HFE{} / HFR
= Perform Zero Cal
= Perform Linear Reset
= Perform Linear Reset at point x (x is # from 1 - 9 or letter ‘A’)
= Perform Linear Cal at point x ( x is a # from 1 - 9 or the letter ‘A’).
= Zero Cal correction.
= Span Cal linear corr. All X's.
= Span Cal linear corr. All S's.
= Span Cal linear corr. All C's.
= Perform Hysteresis cal.
= Hysteresis correction.
Calibration ‘Perform’ command data entry. The LxE{} is used to do calibration and linearization at the span
points. The x is not typed in, but replaced with the number of the cal point you are using. Note that the value
entered inside the braces is dependent upon what the resolution or count by is set to.
COMMANDS:

SETUP DATA
General:
FORMAT:
<par 1>|<par 2>| - - - <par x>
Setup data is set in a string using the separation character '|' between parameters.
The parameters are listed in the order of the function diagram as they appear in the manual.
'Arrow' select parameters are represented as a number starting with '0'.
Numeric entered data is directly represented by its data value.
When entering setup data, the full string of parameters need not be entered.
The following is a summary of the commands available to change in the setup menus. Note that the command with
braces is the command to enter a value and the one that ends in an R is to recall the current value.

RELAYS OVERVIEW (DUAL BAND TRIP OPTION)
General:
The Dual Band Trip Option is a dual band trip (trip point) performed in the meter's CPU on the
processed Torque data. The "Trip Option" provides relay contact closures as well as a visual indication
whenever a recorded data value is in or out of a preset band as set by the configuration. The
Configurable hysteresis settings are included which can be used to decrease drop-out threshold levels
thus minimizing noise effects. Each limit hysteresis can be configured for either ascending or descending
hysteresis application.
The trip band is defined by two trip points with individual hysteresis and polarity settings selected in the
Trip Pt setup.
All settings related to the Trip Points are configured by the operator in the I/O menu under "Trip Pts?"
and are stored in the non-volatile memory.
When enabled by the setup, the Trip Points can be modified from the front panel in the "run" mode.
Specifications:
Number of trip bands:

Output Activation select:
If set for "IN BAND" the output relay is "ON" (energized) when the data
is in the Trip Band. If set for "OUT BAND" the output relay is "ON" when
the data is out of the Trip Band.
Power-up reset Protection: All relays are held "off' until the CPU re-establishes proper operating
conditions caused by power interruptions.
Indicators:
Can be set in configuration for two types of display indications. If set for
"ACCEPT" and selected by the "DISPLAY" key, the alpha display will
indicate "LOW', "ACCEPT" and "HIGH" for trip band 1. If set for "TRIP
PTS", the display will indicate the active outputs by "TRIP 1 ", "TRIP 2",
or TRIP 1 & 2". In this display mode the Units will not be displayed unless
changed by the unit selection keys.

Section 9.0
RPM / HP OPTION
General:
The work (Horsepower) / Speed (RPM) Option is a measurement of speed and the calculation of
horsepower in the meter’s CPU on the processed speed and torque data.
The speed signal is usually taken from a magnetic or Hall Effect sensor mounted on the torque sensor
housing. Each time a gear tooth passes by the sensor a pulse is generated and conveyed to the
indicator. This signal is digitally converted by the indicator to an accurate digital indication of frequency
using a crystal oscillator as a reference. The CPU utilizes the number of gear teeth, as set in the
configuration mode, to derive the speed (RPM) and process the measured frequency. No calibration is
required and the RPM filtering and display resolution is selectable in configuration.
The meter’s CPU calculates the work (horsepower) from the measured RPM and torque data. The
display resolution and filtering are applied to the computed horsepower as set by the configuration. No
calibration of the horsepower is required.
All settings related to the horsepower and RPM are configured by the operator in the I/0 menu under
"RPM/HP ?’ and are stored in the non-volatile memory.

Resolution:
The HP option must be turned on in the I/O menu. See section 4.5 for details on enabling HP.
6. Problem:
113
Horsepower(HP) or Revolutions per Minute (RPM) conversions are not available in the conversions
menu or do not work.
Resolution:
You need to have purchased the meter with the HP/RPM option. Without it, these options will not
work.
Calibration:
Note: For step-by-step instructions on calibration, see section 4.3
7. Problem:
Problems calibrating with the toggle switch S13.
Resolution:
The steps referring to the toggle switch only apply if you are using a shunt cal. If you are using a shunt
cal, be sure that it is seated and that the fastening screws are in tight. Also be sure to hold the switch
long enough when performing the calibration.
8. Problem:
General problems calibrating.
Resolution:
First, remember to have a device connected to the terminal in the rear and to have it set for zero load at
first.
Second, there must be a least one non-zero load for the +span and one non-zero load for the –span. It
is important to add a load when the screen scrolls “+span 1 cal target = xxx”.
Third, although you may use up to 10 data points to calibrate, only one non-zero data point is
necessary.
9. Problem:
“Entry must be > last cal pt.”
Resolution:
You cannot go out of order when choosing data points to calibrate the meter. Start with a small value
and go in order of increasing magnitude.
10. Problem:
“No span cal. Input too small.”
Resolution:
114
The meter essentially uses a linearization to calibrate. If you pick two loads (which could correspond to
points on a graph) which are too close together, the points are approximately the same and there is no
linearization. The meter needs a range in order to extrapolate values.
To fix the problem, choose a larger difference in loads between data points.
Max/Min:
11. Problem:
The Min and Max options do not show up when pressing the left and right arrow keys during normal
operating mode.
Resolution:
These options are off by default and must be turned on in the Config menu. Refer to section 3.3 for
information on enabling the Min and Max options.
12. Problem:
Some of the conversions are wrong.
Resolution:
Note that the display is limited to roughly 6 digits. If you convert to a unit which runs over this limit, the
conversion is incorrect. The meter will not give an error, however. The best approach is to use
common sense when choosing units and doing conversions.
Ram Reset:
13. Problem:
Any of the following symptoms can occur after the RAM has been reset to factory defaults.
"Lost -span cal. perform the -span cal" scrolls continuously in normal operating mode.
"Lost +span cal. perform the +span cal" scrolls continuously in normal operating mode.
"No conversions selected" when pressing the up or down arrows
The serial port information will also be reset.
Resolution:
If the RAM was reset, all changes you made have been lost. Your will want to refer to section 4.3 to
recalibrate the meter. This will get rid of the "Lost ±span cal. Perform the ±span cal" errors. Then,
refer to section 4.5 for instructions on how to enable the conversions and section 4.5 for instructions on
how to enable the HP/RPM option. This will remedy the "No conversions selected" error. Finally, turn
on the “Zero Set” option under the Config. menu to correct the "Key inactive" error when hitting the
zero key.
Zero:
14. Problem:
“Out of Zero Negative band”
Resolution:
115
Go to the config menu (see section 4.3) and increase the value of “Zero Set”
Serial Data:
15. Problem:
There is no display on the screen from the meter
Resolution:
The terminal program you are using is not set up correctly or not very compatible. Try a different
terminal emulator.
16. Problem:
There is no display on the screen from the meter
Resolution:
The cable you are using may not be correct or may be damaged. If possible, try another cable or try
the cable with another device.
17. Problem:
There is no display on the screen from the meter
Resolution:
There could be a problem with the serial port or its configuration on the computer or equipment you are
using. If available, try using the second serial port on the computer or equipment.
18. Problem:
There is no display on the screen from the meter
Resolution:
Ensure that the software is set with the correct COM port. Typically a computer serial port will use
Com 1, 2, 3, or 4. Try using a different COM port number. Also be sure that the port is open and
ready to receive information.
19. Problem:
There is no display on the screen from the meter
Resolution:
The display option must be set to echo to see the text. Refer to section 6.2 for the best settings to
establish a connection.
20. Problem:
Pressing the PRINT key does not display the meter value on the screen.
Resolution:
116
The printer option must be set to On for this to work. Refer to section 6.2 for instructions on how to
change this setting.
General Problems:
21. Problem:
I cannot enter any of the special configuration modes.
Resolution:
If any more than one dip switch is closed, the meter will default to the normal operating mode. Set all 4
dipswitches to OPEN and then close just one.
22. Problem:
“No Tare” message when pressing the TARE key on the front panel.
The Fixed Tare function is not working.
Resolution:
The “Zero Set” must be set to “Autotr” within the config. menu.
23. Problem:
Digital Input/Output is not working correctly.
Resolution:
Ensure that the two jumpers are set correctly. For Digital input, see sections 5.1 and 5.2 . For Digital
output, see section 5.3.
24. Problem:
Freeze mode is not even an available option on the menu.
Resolution:
Freeze mode must be turned on in the config. menu. For details on enabling freeze mode, see section
5.2.
