Accessing Calibration Potentiometer
You will need to remove the power supply’s cover to access the
programming and readback calibration potentiometers which are located
on the A2 PCB. See Figure 5-1 to locate the potentiometers.
Removing Option Card
If there is a GPIB or RS-232 option card (PCB) installed inside the power
supply, you will have to remove it to access the calibration
potentiometers.
Tool Required: Phillips #2 screwdriver
To remove the option card:
1. Turn OFF the power supply. Disconnect AC Power. Remove the
cover.
2. Remove four screws from their standoffs inside the power supply to
release the option card.
3. Remove two screws at the rear panel to release the option card’s
subplate.
4. Unplug the ribbon cable connectors from the option card. Lift out
card.
WARNING
Disconnect AC power from the unit before removing the cover. Even with the front
panel power switch in the OFF position, live line voltages are exposed when the
cover is removed. Repairs and adjustments must be made by experienced service
technicians only.
WARNING
Use a non-conducting, straight-bladed screwdriver to adjust the trim pots.
CAUTION
Follow established antistatic procedures. There are static-sensitive parts on the
printed circuit boards.
