Measuring AC Voltage
Voltage levels of up to 600 volts AC can be measured with
your insulation resistance tester. With test leads installed:
1. Ensure power is on (DMEG3).
2. Place rotary function select switch to the
“
AC 600 V
” position.
3. Connect black test lead to the grounded or neutral
side of the circuit.
4. Connect red test lead to the hot or powered side of
the circuit.
5. Apply power to the circuit under test.
6. Press and hold (or lock) the “
Press to Test
” button.
7. Observe voltage level.
8. Release the “
Press to Test
” button, remove power to the
circuit under test and then disconnect test leads.
WARNING!
Connecting alligator clips to live circuits presents a shock
hazard. Insulation on these clips deteriorates over time and
often wears thin from the inside, through use,. If live voltage
must be tested, connect the black clip to a KNOWN ground
then use the red test lead without the alligator clip attached
to check the hot side of the circuit. Use protective clothing and
equipment when appropriate.
