Operation
WARNING: Risk of Electrocution. Before use, always test the
Voltage Detector on a known live circuit to verify proper
operation
AC Current Measurements
1) Set the Function switch to the ACA range.
2) Press the jaw trigger and clamp around,
a single conductor.
3) Do not allow a gap between the two halves of the
jaw.
4) Refer to the diagram at right for
The correct way to enclose a single conductor.
5) Read the ACA value on the LCD.
Non-Contact AC Voltage Measurements
1) Touch the probe tip to the hot conductor or insert into the hot side of
the electrical outlet.
2) If AC voltage is present, the detector light will illuminate.
NOTE: The conductors in electrical cord sets are often twisted. For best
results, rub the probe tip along a length of the cord to assure
placing the tip in close proximity to the live conductor.
NOTE: The detector is designed with high sensitivity. Static electricity or
other sources of energy may randomly trip the sensor. This is
normal operation
