POINTS OF CAUTION
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +70°C
(23 to 158°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

Torque: 0.6 N·m
CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Input: Check that the input voltage is within 0 – 100% of
full-scale.
If the thermocouple or its extension wires are broken, the
output goes over 100% (below 0% with downscale) due to
burnout function. Check leadwires in such a case.
3) Output: Check that the load is within the permissible
limit including wiring resistance.
Load Resistance (Ω) = Supply Voltage (V) – 13 (V)
0.02 (A)
(including leadwire resistance)
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any cali-
bration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.
■PREPARATION
1) Loosen Screw (A) on top and open the covering.
2) Remove Screw (B) so that internal adjustment potenti-
ometers are exposed.

■INPUT BIAS ADJUSTMENT (0% temperature)
Check first electromotive force (mV) for 0% (and 100%) tem-
perature in Thermocouple Reference Table.
1) Close across the front terminal 2 – 3 and remove tem-
perature sensor connected to voltage generator as in the
above illustration. (Canceling cold junction compensa-
tion)
2) Connect a digital voltmeter across the front terminal 2
(–) and TP1 (+).
3) With minimum (0%) input, adjust SW2 to appropriate po-
sitions – nearest to desired value – according to Table 1
[INPUT BIAS SELECTION TABLE], and adjust output
reading to 0 ±0.002V with VR5 (zero-coarse adjustment).
4) With minimum (0%) input, adjust output to 0 ±0.05%
with VR1 (zero-fine adjustment).
■INPUT RANGE ADJUSTMENT (100% temperature)
5) With maximum (100%) input, adjust SW3 to appropriate
positions according to Table 4 to Table 6 [INPUT RANGE
SELECTION TABLE], and adjust output to 100 ±0.05%
with VR4 (span-coarse adjustment) and VR2 (span-fine
adjustment).
6) With minimum (0%) input, check that input is 0 ±0.05%.
When the ZERO point is changed, repeat the procedure
2) to 5).
■COLD JUNCTION COMPENSATION ADJUSTMENT
7) Connect temperature sensor to the voltage generator
again and remove shortcircuit across the terminal 2 – 3.
8) With minimum (0%) input, adjust output reading to 0%
with VR3.
■OUTPUT ZERO & SPAN ADJUSTMENT
1) ZERO: Apply 0% input and adjust output to 0% with the
VR1.
2) SPAN: Apply 100% input and adjust output to 100% with
the VR2.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above proce-
dure 1) – 3).
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the “ADJUST-
MENT PROCEDURE” explained earlier.
LIGHTNING SURGE PROTECTION

Note 1: The SW2-1 is turned ON (1) with suppressed zero
range, while it is turned OFF (0) with elevated zero
range.
Note 2: With suppressed zero range, weight of bit (mV) is
added by turning ON (1) each one of the SW2-8 to
SW2-2, while with elevated zero range, it is added by
turning OFF (0) the same.
For example, 20mV bias (zero suppression) is nearly
obtained by turning on SW2-1 (positive), SW2-4 and
SW2-8 (19mV + 1.2mV = 20.2mV).
Note 3: When the test pin reads a positive voltage, turning one
bit ON (1) decreases the bias.
When the test pin reads a negative voltage, turning
one bit OFF (0) increases the bias.

Note 1: Gain indicates the multiplying factor adjustable with
SW3.
Note 2: Gain is calculated by using the following equation:
Gain = 2000 (mV)
20 (V100% – V0%)
Where V100% = input span
V0% = input zero
Add an weight of bits according to the gain value.
For example, with 0 – 4.2mV input, the calculated
gain, 23.8, is rounded to either 23 or 24.
Then turn off (0) SW3-3 and SW3-7.
Alternately, turn off (0) SW3-3, SW3-7 and SW3-8.
