a.
ZERO Calibrations (always done first).
The only means of adjustment is the
CAL:DATA <VALUE>
command which provides a total of 4095 increments of adjustment start-
ing at 0, with 2047 increments in either direction to achieve maximum output levels of ±2.5% of
E
Onom
. Adjust the output to obtain the closest value to zero.
b.
MAX and MIN Calibrations.
The primary means of adjustment is the
CAL:DATA <VALUE>
command to either increase (
CAL:DATA 1
) or decrease (
CAL:DATA -1
) the output value.
Adjustment can be done in larger increments by increasing the numeric value, e.g.,
CAL:DATA +10
or
CAL:DATA -10
. Adjust the output to obtain the closest value above the full
scale value.
c.
VPR and CPR Calibrations.
The only means of adjustment is the
CAL:DATA <VALUE>
command which provides a total of 4095 increments of adjustment from zero to maximum.
Adjust the output to obtain the closest value above the full scale value.
4.3.1
CALIBRATION PROCEDURE USING SCPI COMMANDS
The following procedure provides a complete calibration of the unit. Steps 17 and 18 calibrate
the control signal used when the unit is a slave in series configurations. Steps 28 and 29 cali-
brate the control signal used when the unit is a master in parallel configurations. Steps 31 and
32 calibrate the control signal used when the unit is a slave in parallel configurations. There is
no need for a special calibration step when the unit is used as a master in series configurations
since the BOP output voltage (which is calibrated by this procedure) is used to control the next
unit in series.
NOTES:
1.
For ZERO calibration, adjust output to obtain value closest to zero.
2.
For FULL SCALE calibration adjust the output to obtain the closest value above
the nominal full scale value.
3.
Set the unit for local sensing with GND Network in (see Figure 4-1) and discon-
nect load from BOP output to prepare the unit for voltage calibration.
CAUTION: Sending commands other than SYST:ERR? during calibration will adversely
affect calibration of the unit.
