2. With no load connected, set POWER switch to the ON position. Each time the unit is turned
on an internal self-test is performed. The alphanumeric display (LCD) shows the processor
firmware revision history and lists various tests performed during the internal self-test. As
each test is completed, PASS or FAIL is displayed. If all tests pass, the unit goes into the
default mode. If a failure occurs, the failure is displayed. Figure 3-3 shows the factory config-
ured power on defaults displayed on the LCD.
3. Connect a digital voltmeter (DVM) (resolution and accuracy of 0.01% or better) to the
OUTPS and COMS terminals at the rear panel terminal block.
4. Use the keypad to enter the rated maximum voltage of the power supply (e.g., enter 36 for a
model BOP 36-28MG) and press ENTER . If STANDBY indicator is lit, press STANDBY key.
5. Verify DVM voltage reading agrees with programmed voltage within 0.03% of rated maxi-
mum voltage and agrees with displayed voltage on LCD within 0.05% of rated maximum
voltage.
