TESTING FOR CONTINUITY
Continuity tests are made to check for breaks in a circuit, such as
the switch, light bulb, or electrical cable as shown. To make a
Failure to do the following step can damage the multimeter.
Disconnect the circuit being tested. To be safe, disconnect the
battery ground strap.
Connect the meter probes to both terminals of the circuit being
tested. (The AN/ URM-105 is illustrated, but the probes are con-
nected to the circuit the same way with all three multimeters.)
D Observe needle movement.
If the needle swings to the far right over the 0 on the top scale, the
circuit has continuity.
If the needle doesn't move, the circuit is open (broken).
If the needle jumps or flickers, there is a loose connection in the
circuit being tested.
