CHECKING
The shape of base socket may be different
for some models.
■ FRONT PANEL CONFIGURATIONS
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
–␣ 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the described specifications.

ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.
■ HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) ZERO: Apply 0% input and adjust output to 0%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above procedure
1) – 3).
POINTS OF CAUTION
■ GENERAL
•Before you remove the unit from its base socket or mount it,
turn off the power supply and input signal for safety.
■ WIRING
• Do not install cables (power supply, input and output) 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.
■ AND ....
• The unit is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.
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 accuracy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the "ADJUSTMENT PROCEDURE" explained earlier.
■ ENVIRONMENT
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +50°C (23
to 122°F) with relative humidity within 30 to 90% RH in order
to ensure adequate life span and operation.
