6.3 Breaker Finder Operation Guide
With the probe kit connected to power, select Mode II on the tool kit working mode switch
button.
Switch on the breaker nder and set the rota switch to the middle position. Press and hold
the TEST button, and move the black probe tip along the wire you want to test. The breaker
nder detects the signal and sound the loudspeaker which means the unit is working
correctly.
Connect the black test lead to the negative supply(ground) and red test lead to the positive
supply(or a fuse socket, connector for more convenient connection). Switch on the breaker
nder probe and set its rota switch to the middle position, press and hold the TEST button
and slowly sweep the wire with the probe point above or below perpendicularly and as
close as possible. Check at dierent points of the wire to narrow it down rst or tracing the
wire all along, moving towards the end with load.
Obsee the tone signal. Where the tone signal stops, it’s the location of the open, break or
bad connection of the circuit.
If it’s dicult or impossible for the breaker nder to pick up any tone signal, please t
increase the sensitivity by turning the rota switch of the breaker nder clockwise and test
again.
When you have nished locating open circuit, disconnect the test leads and let go of the
TEST button.
