c. Continuity Tests. Continuity tests are made to check for breaks in a circuit (such as the
switch, light bulb, or electrical cable illustrated). To make a continuity check (Fig. 5-5), do the
Failure to perform the following step can damage the multimeter.
(1) Disconnect the circuit being tested. To be safe, disconnect the battery ground strap.
(2) Set up and zero the multimeter.
(3) Connect the meter probes to both terminals of the circuit being tested. (The
TS-352B/U is illustrated below, but the probes are connected to the circuit the same way with each
of the three multi meters.)
Figure 5-5. Making a Continuity Check
(4) Look at the meter needle.
(a) If the needle swings to the far right over the O on the top scale (on all
three multimeters), the circuit has continuity.
(b) If the needle doesnt move, the circuit is open (broken).
(c) If the needle jumps or flickers, there is a loose connection in the circuit being
