(23 to 131°F) with relative humidity within 40 to 85% RH in
order to ensure adequate life span and operation.
■ 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.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Auxiliary power supply voltage: Check voltage supplied to
the rack (model: 17BXE). Use a power source of ripple
level 10% p-p or less.
3) Input: Check that the input voltage is within 0 – 120%
of the rated voltage.
4) Output: Check that the load resistance meets the described
specifications.
ADJUSTMENT 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 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 auxiliary 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).
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 toler-
ance, recalibrate the unit according to the "ADJUSTMENT
PROCEDURE" explained earlier.
LIGHTNING SURGE PROTECTION
In order to protect the unit from lightning surges entering
through signal and power supply cables, use of appropriate
lightning surge protectors are recommended. Please contact
M-System.
