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.

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).
