32.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.
33.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.
NOTE: Accuracy of the 10V d-c reference must be ±0.1mV in order for the calibrated unit to
meet published specifications.
34.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.
35.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.
4.3.2 CALIBRATION OF SERIES- OR PARALLEL-CONNECTED UNITS
Calibrate each individual unit to be used in the multi-unit configuration as a standalone unit (not
connected in parallel or series). Calibration of the series-connected or parallel-connected sys-
tem is not necessary and is not possible.
4.4 CALIBRATION STORAGE
The BOP-GL maintains the calibration tables in Flash Memory until a PACK is executed. There
are six calibration areas maintained in Flash Memory: Working, Prior, Oldest, Factory, Master,
and First.
The calibration can be copied to another area using the CAL:DUMP? and CAL:COPY com-
mand. The syntax is as follows: CAL:DUMP? [source];:CAL:COPY [destination], where [source]
and [destination] refer to the areas of Flash memory where calibration data is stored, designated
as: WORKing, PRIor, OLDest, FACTory, MASTer, FIRst. Source refers to the calibration area
that is to be copied, destination to the area that the calibration will be copied into.
The ability to save to the FACTORY area is prohibited. If a user needs to overwrite the factory
calibration, a special firmware needs to be created to provide a special password for this capa-
bility. Each customer that requests this capability will be provided a password that the company
can specify. it must contain at least one alpha, one numeric and one punctuation character
(!@#$%^&*) and be at least 6 characters long and not longer than 20 characters in length. All
alpha data must be upper case and no control nor space characters are allowed.
