Adjustment Procedure

Adjustment is performed on each channel, one at a time. Additionally, voltage output and current output each use unique calibration constants. If desired, you may adjust only voltage output or current output.

Preparation Before performing any adjustments, determine if the adjustments are to be temporary or permanent (refer to the discussion on page 155).

If Permanent 1. Turn off the mainframe.

2.Remove the terminal module (see page 26).

3.Remove the module from the mainframe (see page 21).

4.Set the Cal Store Enable Jumper to the CAL position as shown in Figure D-1.

5.Reinstall the module in the mainframe.

6.Make the CAL output terminal connections on the terminal module.

7.Install the terminal module.

8.Apply power and allow a 15 minute warm-up.
