Limitations
The warranty set forth above is exclusive and no other warranty,
whether written or oral, is expressed or implied. Measurement
Specialties specifically disclaims the implied warranties of
merchantability and fitness for a particular purpose.
Some jurisdictions do not allow limitations on how long an implied
warranty lasts, so the above limitation or exclusion may not apply

Three-Year Limited Warranty
►Use
►
two 3.0 x 0.5 mm thread machine screws to attach to
the bottom or rear 15203B/25203B/35203B mount faces
[recommended torque 5 lbf-in (0.56 N.m)]. Be careful not to
bottom screws in tapped holes as this can strip threads.
Connect a 15203B/25203B/35203B to a 35250A, and connect a PC
COM port to the other side of the 35250A using the cable provided.
(If connecting to a PC with only a USB port, an RS232 to USB cable
will be needed). Plug power supply into wall and plug into power
jack on side of 35250A. Accelerometer should then be ready for use.
►A
► light film of oil or silicone grease can be used to enhance
contact between mounting surfaces.

Supply
►A
► locking compound should be used on all threads to prevent
screws loosening due to vibrations.

How to Use the 15203B / 25203B / 35203B
as an Analog Sensor
►If
► a Measurement Specialties 35250A PC Interface Adapter
is available, connect its sensor connector to the
15203B/25203B/35203B, apply power to the 35250A, and connect
a computer to the 35250A RS232 connector. A positive acceleration
(labeled on the accelerometer cover) causes a positive change on the
corresponding output.
►If
► a 35250A is not available, connect a +8.5 to 36V DC power
source to +Vs. Connect power source ground to the Gnd pin.
Connect a computer RS485 interface to the two RS485 pins on the
15203B/25203B/35203B.
►Optionally,
►
connect a voltmeter or other instrument to each
15203B/25203B/35203B Analog Output and Signal-. For best
results, use a converter with an input impedance greater than 1MΩ.
►Keep
►
cable lengths between an analog output and an instrument as
short as practical. Use shielded twisted pair wiring, especially near
electric motors or other noise sources.
►Download
►
Instrument Configuration Utility (ICU) software
from precisionsensors.meas-spec.com and use it to configure the
15203B/25203B/35203B. When transmitting High Speed Data to a
PC, sample frequency should be at least 10 times the filter bandwidth
when linear interpolation is used for signal reconstruction. Built-in
low-pass filtering can be used to lower the noise floor and eliminate
spurious peak measurements from short-duration shock impulses
with insignificant energy content.

your application.
►Inversion
►
of the sensor channels (Invert). Each channel
output can be inverted for maximum flexibility in your
measurements.
►The
►
telemetry Bit Rate may be adjusted according to how
fast measurements need to take place. RS232 hardware
limits bit rate to 115kb.
Retrieving the Calibration Certificate
1.Connect to the unit with ICU.
2.At the bottom of the Configure window, click Reports.
3.A separate window opens with Report selections at the bottom.
Select the Calibration check box. The certificate will then be
displayed.

►First,
►
uninstall any previous versions of ICU that may be
installed, then download Instrument Configuration Utility
(ICU) software from precisionsensors.meas-spec.com. Run
Setup_ICU.exe to install ICU.
►Start
►
ICU. Use About/Setup to select your COM Port
and confirm the data directory. Select Configuration as the
Program Function and press OK.
►Press
►
the Configuration button. ICU scans for any
instruments attached to the COM Port. If an instrument is
found, ICU connects and reads the instrument configuration.
►The
►
15200B/25200B/35200B comes ready from the factory.
If your application requires changes, use the Main tab
to change the telemetry and the channel tabs to edit each
channel. For each channel, check the Range Hi and Range
Lo and the Filter 3dB Cutoff. If changes are made, you must
press the Write Values to Instrument button. The password
as shipped from the factory is “si”.
►Use
►
the High Speed Acquire button to collect and save data
to disk.
