Calibrating Voltage

Calibration may cause dangerous voltages to be present at the power module output.

The following procedure calibrates the output voltage and the overvoltage protection (OVP). During voltage calibration, you will enter two readings from the external DVM. You must calibrate the voltage before calibrating the OVP. You do not have to enter any external readings when calibrating the OVP.

Function

 

Connect the equipment as shown in Figure A-lA

Output Voltage Calibration

 

 

 

 

 

*RST

Reset the power module

(Before proceeding, set the module output, via the keyboard or the GPIB, for 1.0 V at 0.5 A)

 

 

OUTP ON

Enable the output

 

 

CAL:STAT 1,66102

Using your password, enable the calibration

 

 

 

 

 

mode

 

 

CAL:VOLT:LEV MIN

Select the lower calibration point

 

 

CAL: VOLT: DATA <NRf>

Enter the digital voltmeter reading

 

 

 

 

CAL:VOLT:LEV MAX

Select the upper calibration point

 

 

 

 

CAL:VOLT:DATA <NRf>

Enter the digital voltmeter reading

 

 

 

 

 

 

Note: The following step overwrites the existing voltage calibration constants stored in nonvolatile memory.

CAL:SAVSave the new calibration constants

Overvoltage Protection Calibration

If the optional output relay is installed, either disconnect it or set it to the OFF (open) state.

CAL:VOLT:PROT

Perform OVP calibration

Note: It takes a few seconds for the power module to make the measurement. When completed, the new constant is automatically stored in nonvolatile memory.

†See Figure A-2 for program listing.

‡Enter the voltage measured by the external digital multimeter.
