REMOTE MONITOR OUTPUTS CALIBRATION
Remote Monitor output signals can be calibrated with set of commands as described in
below section. For detailed Pin description of the Remote Monitor Outputs and connection
diagram, Refer Section 8.4
13.7.1
Voltage Monitor Output Calibration
STEP DESCRIPTION
1. Issue a *CLS command.
2. Issue a *RST command.
3. Connect the DMM at PIN 7 (VMON1) and PIN 6 (MON_RTN) for channel 1,
PIN 7 (VMON2) and PIN 6 (MON_RTN) for channel 2 and PIN 7 (VMON3) and
PIN 6 (MON_RTN) for channel 3 to measure voltage monitor pin voltage and
Set the load for approximately 25% of rated output current respected channel.
Type the following commands.
SOUR<n>:VOLT 0
SOUR<n>:CURR <100% channel current rating>
OUTP<n>:STAT 1

CAL<n>:INIT:VOLT:MON
4. Calibrate the Offset point.
CAL<n>:OUTP:VOLT:MON:OFFS <voltage at PIN7 read from DMM>
5.
Set the output voltage to 80% of channel Full-scale rated voltage.
SOUR<n>:VOLT <0.8 times channel Full-scale voltage>
CAL<n>:OUTP:VOLT:MON:FSC <voltage at PIN7 read from DMM>
6. Store the Calibration.
