BOP-1K 031014
NOTE: Accuracy of the 10V d-c reference must be ±0.1mV in order for the calibrated unit to
meet published specifications.
32.Connect a +10V ±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 maximum posi-
tive output current by sending
CAL:PAR MAX
. Measure the output current using the DVM.
Send
CAL:DATA
commands as needed (see PAR. 4.3b) until the DVM reading is as speci-
fied in Table 4-3 for +FULL SCALE CURRENT.
33.Save the calibration levels by sending
CAL:SAVE 12/21/2003
. The characters at the end
are optional and represent the calibration date of the power supply. The date entered in this
manner is reported in the
*idn?
query.
