erance specified in Table 4-4 for +FULL SCALE CPR LIMIT.
24.Send
CAL:CPR MIN
to adjust the minimum (maximum negative) current protection limit of
the power supply. To adjust, send
CAL:DATA
commands as needed (see PAR. 4.3c) to
adjust the BOP output until the DVM reads as close as possible above (absolute value) the
nominal full scale value within tolerance specified in Table 4-4 for –FULL SCALE CPR LIMIT.
25.Send
CAL:ZERO
to set the BOP output to zero. Connect 0V ±0.1mV d-c reference voltage to
external reference pin 11 referenced to pin 10 (SGND) of the BOP analog I/O port (A2A5J6).
Set the BOP to zero volts across the sense resistor (corresponding to zero current) by send-
ing
CAL:CEXT ZERO
. Send
CAL:DATA
commands as needed (see PAR. 4.3a)
until the
reading is as close to zero as possible within the limits specified in Table 4-4 for CURRENT
ZERO.
26.Replace the 0V d-c reference applied to analog I/O port A2A5J6 pin 11 with a +10V ±0.1mV
d-c reference voltage. Set the BOP to maximum positive output current by sending
CAL:CEXT MAX
. Measure the current by reading the voltage across the sense resistor. To
adjust, send
CAL:DATA
commands as needed (see PAR. 4.3b) to adjust the BOP output
until the DVM reads as close as possible above the nominal full scale value within tolerance
specified in Table 4-4 for +FULL SCALE CURRENT.
27.Replace the +10V d-c reference applied to analog I/O port A2A5J6 pin 11 with a 0V ±0.1mV
d-c reference voltage. Set the BOP to zero volts across the sense resistor (corresponding to
zero current) by sending
CAL:CGA ZERO
. Send
CAL:DATA
commands as needed (see
PAR. 4.3a)
until the reading is as close to zero as possible within the limits specified in Table
4-4 for CURRENT ZERO.
28.Replace the 0V d-c reference applied to analog I/O port A2A5J6 pin 11 with a +10V ±0.1mV
d-c reference voltage. Set the BOP to maximum positive output current by sending
CAL:CGA
MAX
. Measure the current by reading the voltage across the sense resistor. To adjust, send
CAL:DATA
commands as needed (see PAR. 4.3a) to adjust the BOP output until the DVM
reads as close as close to zero as possible within the limits specified in Table 4-4 for CUR-
RENT ZERO.
29.Send
CAL:ZERO
to prepare for calibration of IOUT_M_UNIT (master output) control signal.
Connect the DVM to pin 6 (IOUT_M_UNIT) referenced to pin 1 (SGND) of the PAR/SER
CONTROL IN connector (A2A5J3). Set the BOP to zero output current by sending
CAL:IOUT ZERO
. Send
CAL:DATA
commands as needed (see PAR. 4.3b) to adjust the
BOP output until the DVM reads 0V ±1mV.
30.Set the BOP to maximum positive output current by sending
CAL:IOUT MAX
. With the DVM
still connected to pin 6 (IOUT_M_UNIT) referenced to pin 1 (SGND) of the PAR/SER CON-
TROL IN connector measure the voltage output using the DVM. Send
CAL:DATA
commands
as needed (see PAR. 4.3b) until the DVM reading is +10V ±1.0mV.
31.Send
CAL:ZERO
to prepare for calibration of S_IN_PARALLEL (slave input) control signal.
Connect a 0V ±0.1mV d-c reference to pin 3 (S_IN_PARALLEL) referenced to pin 1 (SGND)
of the PAR/SER CONTROL IN connector (A2A5J3). Set the BOP to zero output current by
sending
CAL:PAR ZERO
. Connect the DVM across the sense resistor to measure the BOP
output current and send
CAL:DATA
commands as needed (see PAR. 4.3b) to adjust the
BOP output current until the DVM reads as close to zero as possible within tolerance speci-
fied in Table 4-4 for CURRENT ZERO.
