Calibrating Current

The following procedure calibrates the output current. During the calibration, you will make two voltage measurements
across the output shunt and enter the computed current.

Keyboard Entry

Controller Entry †

Function

OUTP OFF

Disable the output

Connect the equipment as shown in Figure A-lB.

(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:CURR:LEV MIN

Select the lower calibration point

Wait for the meter reading to stabilize. Then read the meter and enter the calculated current value.‡

CAL: CURR:DATA

Enter lower current value

CAL:CURR:LEV MAX

Select the upper calibration point

Wait for the meter reading to stabilize. Then read the meter and enter the calculated current value.‡

CAL: CURR: DATA < NRf>

Enter the upper current value

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

CAL:SAV

Save the new calibration constants

† See Figure A-2 for program listing.

‡ Calculate the current value as follows:
