(5-COMPONENT ANALYZER)
ZKJ
DATA SHEET
This gas analyzer (ZKJ) is capable of measuring the concentrations of NO, SO2, CO2, CO, CH4, N2O and O2 components in sample gas.
NO, SO 2, CO 2, CO, CH 4 and N 2O are measured by nondispersion infrared method (NDIR), while O 2 is measured
by built-in type paramagnetic method sensor or externalmount type zirconia method sensor. A maximum of 5
components including O2 (max. 4 components except for
O2 measurement) are simultaneously measurable.
The mass flow type twin detector of high sensitivity and
reliability adopted in the infrared ray method detection
block makes the measurement hardly affected by interfering components.
In addition, a microprocessor is built in and a large-size
liquid crystal display is equipped for easier operation,
higher accuracy and more functions.

Standard Functions
Output signal holding:
Output signals are held during manual
and auto calibrations by activation of
holding (turning “ON” its setting).
The values to be held are the ones just
before start calibration mode or setting
value.
It is selectable.
Indication of instantaneous values will
not be held.
Remote output holding:
Output signal is held at the latest value
or setting value by short-circuiting the
remote output holding input terminals.
Holding is maintained while the terminals are short-circuited. Indication of
instantaneous values will not be held.
Switch ranges :
The switch ranges is available in manual, auto, and remote modes. Only preset switch method is effective.
Manual:
Allows range to switch by key operation.
Auto:
Allows range to switch from low to high
range when 90%FS or more is available
in the low range.
Allows range to switch from high to
low range when 80%FS or less is available in the low range.
Remote:
No-voltage contact input (for measurable components)
Allows range to switch via an external
signal when remote range switch input
is received.
When the contact input terminals for
each component are short-circuited,
the first range is selected, and it is
switched to the second range when the
terminals are open.
Range identification signal:
The present measuring range is identified by a contact signal.
The contact output terminals for each
component are short-circuited when
the first range is selected, and when
the second range is selected, the terminals are open.
Auto calibration:
Auto calibration is carried out periodically at the preset cycle.
W h e n a s t a n d a r d g a s c y l i n d e r fo r
calibration and a solenoid valve for
opening/closing the gas flow line are
prepared externally by the customer,
calibration will be carried out with the
solenoid valve drive contacts for zero
calibration and each span calibration
turned on/off sequentially at the set
auto calibration timing.
Auto calibration cycle setting:
Auto calibration cycle is set.
Setting is variable within 1 to 99 hours (in
increments of 1 hour) or 1 to 40 days (in
increments of 1 day).
Gas flow time setting:
The time for flowing each calibration
gas in auto calibration is set.
Settable within 60 to 900 seconds (in
increments of 1 second)
Auto calibration remote start:
Auto calibration is carried out only once
according to an external input signal.
Calibration sequence is settable in the
same way as the general auto calibration.
Auto calibration is started by opening
the auto calibration remote start input
terminals after short-circuiting for 1.5
seconds or longer.
Auto zero calibration:
Auto zero calibration is carried out periodically at the preset cycle.
This cycle is independent on “Auto calibradion” cycle.
When zero calibration gas and solenoid
valve for opening/closing the calibration
gas flow line are prepared externally
by the customer, zero calibration will
be carried out with the solenoid valve
drive contact for zero calibration turned
on/off at the set auto zero calibration
timing.
Auto zero calibration cycle setting:
Auto zero calibration cycle is set.
Setting is variable within 1 to 99
hours (in increments of 1 hour) or
Setting is variable within 1 to 40 days
(in increments of 1 day)
Gas flow time setting:
The timing for flowing zero gas in
auto zero calibration is set.
Settable 60 to 900 seconds (in increments of 1 second)
High/Low limit alarm:
Alarm contact output turns on when
measurement value reach to the preset
high or low limit alarm value.
Contacts close when the channel value
of each channel becomes larger than
the high alarm limit value or smaller
than the low alarm limit value.
Instrument error contact output:
Contacts close at occurrence of analyzer error No. 1, 3 or 10.
Calibration error contact output:
Contacts close at occurrence of manual
or auto calibration error (any of errors
No. 4 to 9).
Auto calibration status contact outputs: Contacts close during auto calibration.
Pump ON/OFF contact output:
During measurement, this contact
close. While calibration gas is flowing,
this contact open. This contact is connected in power supply of pump, and
stop the sample gas while calibration
gas flowing.

Optional Functions
Performance
O2 conversion: Conversion of measured NO, SO 2 and
CO gas concentrations into values at
standard O2 concentration
Conversion formula: C =
21–On
× Cs
21–Os
C : Sample gas concentration after O 2
conversion
Cs: Measured concentration of sample
gas
Os: Measured O2 concentration
(Limit settable, 1 to 20%O 2)
On: Standard O 2 concentration (value
changeable by setting; 0 to 19%O2)
Average value after O2 conversion and O2 average valu
ecalculation: The result of O2 conversion or instantaneous O2 value can be outputted as an
average value in the preset period of
time.
Used for averaging is the moving average method in which sampling is carried out at intervals of 30 seconds.
(Output is updated every 30 seconds.
It is the average value in the determined period of time just before the
latest updating.)
Averaging time is settable within 1 to
59 minutes (in increments of 1 minute) or 1 to 4 hours (in increments of 1
hour).
Average value resetting:
The above-mentioned output of average
value is started from the initial state by
opening the average value resetting input terminals after short-circuiting for 1.5
seconds or longer.
Output is reset by short-circuiting and
restarted by opening.
CO concentration peak count alarm:
(added only for CO/O2 measurement)
Alarm output turns on according to the
preset concentration and count.
Whenever the instantaneous value of
CO exceeds the preset concentration
value, count increments. If the count
exceeds the preset value in one hour,
the alarm contacts close.

Note 4 Measuring range can be selected within either the minimum or maximum range.
(Within min. or max. range, you can change the actual range settings locally.)
Initial setting from Fuji factory is Min. range for the 1st range, and Max. range for the 2nd range.
When range preset at Fuji factory is required, please select “specified range” at 23rd digit and inform Fuji of specified
range table.
Refer to Table 1, for possible combination of measuring components and ranges in the data sheet.
Note 5 “1E” can be specified at 11th & 12th digits, ONLY for CO2 measurement.
In this case, be sure to select “with purging” at 7th digit.
Note 6 O2 conversion is calculated only for NO, SO2 and CO.
Both average value output after O2 calculation and O2 average value output are provided at the same time.
a) Peak count alarm can be added only for CO measurement.
Note 7 When “Y” is specified at the 6th digit, 22nd digit always has to be specified as “Y”.
Note 8 a) If you would like Fuji to deliver ZKJ analyzer with specific range setting, select “specified range” and separately inform
Fuji of the actual range of each component together with your purchase order.
b) In case that the measurement unit is specified as “mg/m3”, it is necessary to select “unit : mg/m3” (Code “F” or “G”)
at the 23rd digit.
Please refer to the table shown below for the corresponding range code based on “mg/m3”.

Note 9 When “Z” is specified at the 23rd digit, a gas composition table of actual measued gas has to be sent to Fuji
together with your purchase order.
Note 10 When only N2O analyzer is used, make sure not to contain any components other than N2O .
Multicomponent analyzers including N2O analyzer + CO2 analyzer are used for sludge incineration.
In this case, the range of N2O is 0 to 200ppm/500ppm, and the range of CO2 is 0 to 10%/20%.
