Measuring AC Voltage
WARNING!
Do not attempt to make a voltage measurement of more than
600V or of a voltage level that is unknown. Make sure the tem-
perature probe is NOT plugged in during this test.
Instrument set-up:
FUNC. BLACK RED MIN MAX
TEST LEAD TEST LEAD READING READING
COM V/ W 0.1mV 600V
Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the COM input jack.
3 Plug red test lead into the V/
W
input jack.
4. Set rotary switch to the V range.
5. Connect test leads to circuit to be measured.
6. Reconnect power to circuit to be measured.
7. Read the voltage on the 270.
