Ieee 488 Port Input/Output Pin Assignments - KEPCO BOP 1000W Operator's Manual

1. With POWER switch set to off position, connect the power supply to source power (see PAR.
2.5.2).
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.
