CALIBRATION 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 indication to a receiving instrument or in
case of regular calibration, adjust the output as explained in
the following.
■ 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%
following the procedure explained previously in this page.
2) SPAN: Apply 100% input and adjust output indication to
100% following the procedure explained previously in this
page.
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:
■ 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.
