AC voltage adjustment
The following procedure provides instructions for completing a front-terminal adjustment for AC
voltage. The following section provides a command parameter table to complete the adjustment.
For this adjustment, you need a:
•
Fluke 5720 calibrator
•
Keithley Model 3390 function generator
Prepare your DMM6500 for an AC voltage adjustment
To prepare to run AC adjustments:
1. Set the TERMINALS switch to
FRONT
.
2. Connect a cable between the calibrator and the DMM6500 as shown in the figure below.

3. Allow the instrument and cables to settle for 30 seconds.
4. On the calibrator, source
10 mV 1.0 kHz
and allow the calibrator and DMM6500 to settle
properly.
5. Enable the
OPR
key.
6. Ensure that the
