Appendix B Verification and Calibration

Step 5. Select the first voltage calibration point.

CAL:LEV P1 *OPC?

Step 6. Measure the output voltage and enter the data.

CAL:DATA <data>

Step 7. Select the second voltage calibration point.

CAL:LEV P2 *OPC?

Step 8. Measure the output voltage and enter the data.

CAL:DATA <data>

Step 9. Exit calibration mode.

CAL:STAT OFF

Current Programming and Measurement Calibration

Step 1. Connect a precision shunt resistor to an output. Connect the Agilent 3458A across the shunt. The shunt should be able to measure at least 120% of the power supply’s rated full-scale current.

Step 2. Enable current calibration mode.

*RST

OUTP ON CAL:STAT ON

Step 3. Set the output voltage high enough to compensate for any voltage drops on the load leads and current shunt.

VSET 0.5

Step 4. Select current calibration.

CAL:CURR

Step 5. Select the first current calibration point.

CAL:LEV P1 *OPC?

Step 6. Calculate the shunt current (I=V/R) and enter the data.

CAL:DATA <data>

Step 7. Select the second current calibration point.

CAL:LEV P2 *OPC?

Step 8. Calculate the shunt current (I=V/R) and enter the data.

CAL:DATA <data>

Step 9. Exit calibration mode.

CAL:STAT OFF
