Figure 4-6. Zeroing the TS-352 B/U.

(3)

Simpson 160,

Refer to figure 4-7.

(a)

Set the selector switch to RX1.

(b)

Put the black probe in the COM-jack.

(c)

Put the red probe in the + jack.

(d)

Now zero the meter by touching the

probes together and turning the ADJ knob until the

needle is over the (1 on the top scale.

b.

Continuity Tests.

Continuity tests are made to

check for breaks in a circuit (such as a switch, light bulb, or

electrical cable). Make a continuity check as follows:

(1) Zero the meter (para 4-10).

CAUTION

Failure to disconnect the battery ground

cable (or outside power source) can damage

the meter.

(2) Disconnect the battey ground cable at the

battery. Then disconnect the circuit you are going to test.

(3) Connect the meter probes to both terminals

of the circuit you are testing (fig. 4-8).

(4) Read the meter. Interpret the results as

follows:

(a)

If the needle swings over the 0 on the top

scale, the circuit has continuity.

(b)

If the needle doesn’t move, the circuit is

open. The wire is broken and must be replaced.

(c)

If the needle jumps or flickers, there is a

loose connection somewhere in the circuit being tested.

Make sure the meter leads are pressed firmly against the

test points, If the meter lead connections are firm, tighten

all connections in the circuit. If the needle still jumps,

there may be an intermittent open in the wiring; the wire

should be replaced.
