ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibra-
tion.
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.
(Output 1 and Output 2 are linked.)
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 accu-
racy described in the data sheet.  When the output is out of
tolerance, recalibrate the unit according to the "ADJUST-
MENT PROCEDURE" explained earlier.
