Detecting AC Voltage
Any time AC voltage is present on the test leads, the “
Live
Circuit
” indicator light will illuminate. This voltage detection
feature works regardless of battery condition or powering on
the instrument. With test leads installed:
1. Ensure power is off (DMEG3) and the
Press to Test
is NOT pressed.
2. Connect black test lead to the grounded or neutral side
of the circuit.
3. Connect red test lead to the hot or powered side of
the circuit.
4. Observe “
Live Circuit
” lamp.
• Lamp illuminated: circuit is live,
DO NOT
test
continuity or megohms
• Lamp off: circuit is not live, testing may proceed
NOTE:
Connecting the black and red test leads to the specific
sides of the circuit indicated is not critical to the measurement.
Connecting the black “
EARTH
” test lead to ground first is a
safety discipline that can reduce the risk of a shock hazard to
the operator.
