To switch between grounded and ungrounded COM connector:
WCaution
The COM terminal should never be grounded when calibrating
Appliance testers that are powered from the power mains and
not the Calibrator.
1. Press the Setup softkey.
2. Using the cursor keys or rotary knob, highlight Multimeter and either press the
Select softkey or press in on the rotary knob.
3. Using the cursor keys or rotary knob, highlight Ouput GND and either press the
Select softkey or press in on the rotary knob.
4. Using the cursor keys or rotary knob, highlight either GND On or GND Off and
either press the Select softkey or press in on the rotary knob.
5. Return to the multimeter display by pressing the Exit softkey repeatedly.
The Calibrator can measure voltages above 1100 volts when used with a high voltage
probe (Fluke 80K-40) or the standard accessory, the 10 kV divider/resistance multiplier.
Both accessories will divide down the voltage so the multimeter can measure DC voltage
or AC voltage with a frequency of 50 or 60 Hz.
To set the Calibrator for use with a probe, press the Probe softkey until the desired
probe is displayed. There are three choices: No probe, 10 kV, and 40 kV.
The Calibrator can simultaneously measure output voltage and leakage current of hipot
testers.
To make a current leakage measurement using the built-in multimeter:
1. Press M.
2. Select the HIPOT LC mode.
3. If necessary, press the AC/DC softkey to select between ac or dc mode.
WCaution
To prevent possible damage to the Calibrator, never connect
the COM or A connector to the Line (L) terminal of power mains.
