Calibration Procedure
SHOCK HAZARD The next step applies the full output voltage of the power supply to
the output terminals.
Turn off the electronic load before proceeding. If the electronic load is rated less than
the voltage rating of the power supply, you must also physically disconnect the load
from the power supply using the switch as shown in Test Setup A.
Front Panel SCPI Command
A warning message about the full scale out-
put voltage appears on the display.
Select Next.

Step 6. Select the fourth voltage calibration point and enter the data. This is done at full scale voltage.
Front Panel SCPI Command
Display shows: “Enter P4 measured data”
Enter the data from the external DMM.
Press Back repeatedly to back out of the
calibration menu.
CAL:LEV P4
*OPC?
CAL:DATA <data>
Step 7. Save the calibration data.
Front Panel Menu SCPI Command
Select System\Admin\Cal\Save.
Select Save to save the calibration data.
To save calibration data:

Voltage Calibration - With Local Sensing
This procedure calibrates the instrument for Local sense operation (with the +/- sense leads not connected).
Step 1. Turn off the output. Keep all connections as before except disconnect the remote sense leads from the out-
put (see Test Setup A). The unit will automatically revert to local sense mode when the remote sense leads are dis-
connected.
Step 2. Select the local voltage programing and measurement calibration.
Front Panel Menu SCPI Command
Select System\Admin\Cal\Volt\Vloc.
Check that the voltmeter is connected
and select Next.
Specify local sense voltage calibration:
CAL:VOLT
Repeat the remaining calibration procedure (steps 3 through 7) as described under Voltage Calibration - With Remote
Sensing. Other than the first two steps, the remaining calibration steps are unchanged.
