Accessing

Calibration

Potentiometers

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.

WARNING

Disconnect AC power from the unit before removing the cover. Even when the
front panel power switch is 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-blade screwdriver to adjust the trim pots.

!

CAUTION

Follow established antistatic procedures. There are static-sensitive parts on the
printed circuit boards.
