5. Turn the VOLTAGE control (3) clockwise through its range, while observing the front panel
VOLTAGE meter (4). The BOP output voltage should smoothly respond, from the maxi-
mum negative output voltage, through zero, to the maximum positive output voltage of the
BOP.
6. At the rear panel, disconnect the positive voltage connected between pins 2 and 3 of the
OUTPUT ON-OFF port. Verify the front panel VOLTAGE meter shows zero Volts and the
REMOTE OUTPUT ON-OFF indicator goes off.
7. At the front panel, turn a-c circuit breaker/POWER switch (1) to OFF.
8. Connect a short circuit between the OUTPUT (16) and the COMMON (18) terminals on the
front panel.
9. At the rear panel, reconnect the positive voltage between pins 2 and 3 of the OUTPUT ON-
OFF port.
10. Set the BOP front panel controls as follows:
a) Set MODE switch (6), to CURRENT.
b) Set CURRENT CONTROL switch (9), to ON, and rotate CURRENT control (8) to its
maximum counterclockwise position.
c) Set a-c circuit breaker/POWER switch (1) to ON.
11. l
o
MODE indicator (10) will be on and REMOTE OUTPUT ON-OFF (5) indicators will be on.
12. Turn the CURRENT control (8) clockwise through its range, while observing the front panel
CURRENT meter (7). The BOP output current should smoothly respond, from the maxi-
mum negative output current, through zero, to the maximum positive output current of the
BOP.
13. At the rear panel, disconnect the positive voltage connected between pins 2 and 3 of the
OUTPUT ON-OFF port. Verify the front panel CURRENT (7) meter shows zero Amperes
and the REMOTE OUTPUT ON-OFF indicator (5) goes off.
14. Turn a-c circuit breaker/POWER switch (1) to OFF. Remove the short circuit from the out-
put terminals. This concludes the preliminary check-out of the BOP.
