n ENVIRONMENT
• Indoor use
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 0 to 50°C (32 to
122°F) with relative humidity within 40 to 80% RH in order
to ensure adequate life span and operation.
Be sure that the ventilation slits are not covered with cables,
etc. With the vertical mounting, leave at least 5 cm (2 in.) both
at the top and bottom of the unit; with the horizontal mount-
ing, leave at least 2.5 cm (1 in.) at the both sides of the unit.
n 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.
n 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.

CALIBRATION PROCEDURE
This unit is calibrated at the factory to meet the ordered speci-
fications, therefore you usually do not need any calibration.
For matching the indication to a receiving instrument or in
case of regular calibration, adjust the output as explained
in the following.
n HOW TO CALIBRATE THE OUTPUT INDICATION
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 indication to
0%.
2) SPAN: Apply 100% input and adjust output indication to
100%.
3) Check ZERO adjustment again with 0% input.
4)
When ZERO value is changed, repeat the above procedure 1) 3).
MAINTENANCE
Regular checking procedure is explained below:
n CHECKING
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
indication 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 "CALIBRA-
TION PROCEDURE" explained earlier.
