Calibration

Routine calibration should be performed every 12 months. Non-routine calibration is only
required if a related assembly is replaced or if the periodic calibration is unsuccessful.
The calibration involves removing the top cover from the power source. Remove the line
power from the power source before removing the top cover. Some of the adjustments are
on the Oscillator Assembly A4. Other adjustment are on the DC-AC Board Assembly. Refer
to Figure 6-3 for the location of the adjustments.

Routine Calibration

Setup:
Connect the test equipment to the power source as shown in Figure 6-1. Refer to Figure 6-3
for adjustment locations.
The DMM can be connected to the front panel connectors for convenience but will have to be
changed when switching voltage ranges. To avoid this, use the common output terminal at
the rear of the unit.
For best results use the output connectors (Front or Rear) that are typically used.
