- ZERO to set the BOP to zero volts output.
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
%
once.
3. Press
@
- POSITIVE. Measure the voltage output using the DVM. Adjust as needed until
the DVM reading is as close as possible above the nominal full scale value within the toler-
ance specified in Table 4-3 for +FULL SCALE VOLTAGE. Press
%
once.
4. Press
#
- NEGATIVE to set the BOP to maximum negative output voltage and adjust as
needed until the reading is as close as possible above the nominal full scale value within the
limits specified in Table 4-3 for –FULL SCALE VOLTAGE. Press
%
twice.
5. Press
$
- PROTECT,
@
- POSITIVE to adjust the maximum positive voltage protection
limit of the power supply while working in current mode. Adjust as needed until the reading is
as close as possible above the nominal full scale value within the limits specified in Table 4-3
for +FULL SCALE VPR LIMIT. Press
%
once.
6. Press
#
- NEGATIVE to adjust the maximum negative protection limit of the power supply.
Adjust as needed until the reading is as close as possible above the nominal full scale value
within the limits specified in Table 4-3 for –FULL SCALE VPR LIMIT. Press

- ZERO to set the BOP to
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
!
- ZERO. This enables the BOP to recognize that the
voltage at the four _EXTERNAL pins (14, 6, 13, and 5) is 0V. Press
%
once.
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
@
- MAXIMUM. This enables the BOP to recognize
that the voltage at the four _EXTERNAL pins (14, 6, 13, and 5) is 10.0V. Then press
%
three times.
9. Disc10.0V 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).
