Figure A-1. Calibration Test Setup

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:
