3-2 AC Current Measurement
1. Set the function switch to the desired current position.
2. Open the Spring-loaded clamp by pressing the trigger on the right side of the meter.
3. Position the clamp around the wire or the conductor and release the clamp trigger, make sure that the clamp is
entirely closed. The clamp must be positioned around only one conductor of a circuit . If the clamp is placed
around two or more current carrying conductors, the meter reading will be FALSE.
3-3 AC Voltage Measurement
1. Set the function switch to the " V
~
" position.
2. Connect the black test lead to the "COM" terminal and the red test lead to the " V-
Ω
" terminal.
You can now connect the test probes to the circuit to be measured.
3-4 Resistance Measurement
1. Set the function switch at "
< Ω
" position.
2. Connect the black test lead to the "COM" terminal and red test lead to the " V-
Ω
" terminal.
3. Verify that the power to the circuit under test is off. Connect test leads to the circuit to make the measurement.
4. The internal sounder will operate if the resistance of the circuit under test is less than 50
Ω
.
