CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Input: Check current with an ammeter. Be sure that the
connected transmitter allows the unit’s load value [250 Ω
+ output load resistance].
3) Output: Check that output load is within the permissible
limit of 600 Ω.
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.
■HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the input signal on and warm up for
more than 10 minutes.
1) SPAN: Apply 100% input and adjust output to 100%.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 25%, 50%,
75% and 100% input signal. Check that the output signal
for the respective input signal remains within accuracy de-
scribed in the data sheet. When the output is out of toler-
ance, recalibrate the unit according to the “ADJUSTMENT
PROCEDURE” explained earlier.
