Continuity Measurement:
Rotate function selection switch to continuity
measurement position, and turn off the power to
the circuit to be tested
Connect black and red test probe to COM input
jack and respectively.
Measure the circuit to be tested with other ends
of test probes.
If the measured circuit resistance is less than
about 40Ω, the buzzer will sound continuously.
Non-Contact Voltage (NCV)
Hold down the “NCV” key and move the tip of the clamp
toward the conductor under test. If the detected voltage
is ≥ 110V AC (rms), the NCV indicator will flash and the
buzzer will beep.
Note
1)Do not rely solely on NCV detection to determine
the presence of voltage. Detection can be affected
by socket design, insulation thickness, or other factors.
2)lnterference from outside sources could accidentally
trigger the NCV detector.

When measuring resistance or circuit continuity,
to avoid injury or meter damage, turn off the
power to the circuit to be measured and
discharge all capacitors.
