CHECKING
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 de-
scribed specifications shown below.
Check also that the receiving instrument is able to ac-
cept the waveform as explained in the figure below.

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 power supply on and warm up for
more than 30 minutes.
1 ) ZERO: Apply 5% input and adjust output to 5%.
2 ) SPAN: Apply 100% input and adjust output to 100%.
3 ) Check ZERO adjustment again with 5% 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 30 minutes. Apply 0%, 5%,
25%, 50%, 75% and 100% input signal. Check that the out-
put 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 “AD-
JUSTMENT PROCEDURE” explained earlier.
