Calibration 37

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

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:

1 2 ... 32 33 34 35 36 37 38 39 40 41 42 ... 54 55
