2. Press
Connect a Digital Voltmeter (DVM) to the BOP OUT S and COM S terminals to measure the
output voltage. Adjust the BOP output as needed until the DVM reads as close to zero as
possible within tolerance specified in Table 4-3 for VOLTAGE ZERO. Press

zero volts output. Connect 0V ±0.1mV d-c reference voltage from the external voltage source
to the following pins of analog I/O connector (A2A5J6) referenced to pin 12 (GND1):
VLIM+_EXTERNAL (pin 14), VLIM–_EXTERNAL (pin 6), ILIM+_EXTERNAL (pin 13), ILIM–
_EXTERNAL (pin 5). Then press
voltage at the four _EXTERNAL pins (14, 6, 13, and 5) is 0V. Press
NOTE: Accuracy of the 10V d-c reference must be ±0.1mV in order for the calibrated unit to
meet published specifications.
8. Replace 0V ±0.1mV d-c reference voltage at pins 14, 6, 13, and 5 with +10.0V ±0.1mV d-c
reference voltage from the external voltage source referenced to pin 12 (GND1) of the ana-
log I/O connector (A2A5J6), then press
that the voltage at the four _EXTERNAL pins (14, 6, 13, and 5) is 10.0V. Then press
three times.
9. Disconnect +10.0V d-c reference voltage from pins 14, 6, 13 and 6 of analog I/O connector
(A2A5J6). Connect a +0V ±0.1mV d-c reference voltage to EXT_REF, pin 11, referenced to
pin 12 (GND1), of the BOP analog I/O port (A2A5J6).
