Using the Continuity Toner
The continuity function also acts as a toner for use with
an optional tone probe. The signal’s tone and rhythm
increase as resistance decreases. This lets you use a tone
probe to detect changes in resistance between wires in a
cable.
The tester’s continuity beeper is silent above
5 kΩ, but the toner signal is present for all resistance
values.
Figure 24 shows a typical application for the continuity
toner: testing security switches.
To use the continuity toner, refer to Figure 24 and use
the continuity function as described on page 52.
