16 ELECTRICIAN’S MULTIMETER
CONTINUITY MEASUREMENT
WARNING
!
• To avoid damaging the meter or to the device when testing, disconnect
circuit power and discharge all the high-voltage capacitors before
testing for continuity.
• To avoid electric shock, do not input higher than DC 60V or AC 30V
1. Switch the function dial to the position, and make sure the circuit power is turned
off.
2. Connect common test lead to COM terminal, then insert the red test lead to
Hz
V
Ω
° C terminal.
3. Connect the probes to the circuit test points.
4. Measured resistance >30Ω : The circuit is broken; buzzer makes no sound;
red indicator is on.
Measured resistance, <30Ω: The circuit is in good conduction status; buzzer beeps
continuously; green indicator is on.
If “OL “ appears on the screen, the circuit is in open status.
