Testing Continuity
The continuity test measures the resistance of a tested circuit with 2- wire
method at approximately 0.5 mA and determines whether the circuit is intact.
The beeper emits a continuous beep tone when the input resistance value is
less than the approximate 10
W .
Measurement are displayed as below:
1 Press to toggle to the continuity measurement function.
2 Connect the red and black test leads to the input terminal as shown in
Figure 2- 10.
3 Probe the test points and read the display.

CAUTION
Disconnect circuit power and discharge all high-voltage capacitors before testing the
circuit continuity to avoid damaging the multimeter or the device under test.
