4.

Press and hold the gold button for five seconds. (The multimeter beeps twice

when the gold button is first pressed and then two more beeps follow after

five seconds.)

5.

Press the SETUP button and wait for the calibration to finish (CAL is

displayed during the calibration). After the calibration is completed, press

EXIT SETUP (blue button).

6.

Turn the calibrator output off.

7.

Disconnect the calibrator from the multimeter.

Adjustments Part 2

To perform the following procedure, you must lift out the entire circuit board

assembly from the top case half to access the adjustments. Perform this proce-

dure only if the 

Performance Verification

 procedure indicates that the AC voltage

accuracy checks above 60 Hz is out of specification.

Figure 4: Adjustment locations 2

Perform the following steps to adjust the AC voltage calibration above 60 Hz.

1.

Set the multimeter dial to V .

2.

Lift the circuit board assembly out of the top case half.

3.

Connect the outputs of the calibrator to the 

�

C V 

�

 

�

 and COM input

connectors of the multimeter.

4.

Set calibrator to output 100 VAC at 10 kHz (sinewave).

5.

Adjust VC3 until the display shows +98.60 V.

6.

Set the calibrator frequency to 500 Hz (sinewave).
