Operation
NOTES
: Read and understand all
Warning
and
Caution
statements in this operation manual prior
to using this meter. Set the function select switch to the OFF position when the meter is not in use.
Non-Contact Voltage Detector
WARNING:
Risk of Electrocution. Before use, always test the Voltage Detector on a known live
circuit to verify proper operation
.
1.
Rotate the Function switch to any measurement position.
2.
Place the detector probe tip on the conductor to be tested.
3.
If AC voltage is present, the NCV detector light will turn on with
a steady red light.
NOTE
: The conductors in electrical cord sets are often twisted. For
best results, move 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.
AC Current Measurements
WARNING:
Disconnect the test leads before making clamp measurements.
1. Rotate the Function switch to the
200A
position
2. Press the trigger to open jaw. Fully enclose
only one conductor.
3. Read the current value in the display.
4. If the value is less than 40A, rotate the function
switch to the
20A
position to improve
resolution.
