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.

	Table A-3. Current Calibration Procedure
Keyboard Entry		Controller Entry †	Function
		OUTP OFF	Disable the output
		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 <NRf>	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:
