Checking Continuity
Checking Continuity
The PRO3000 toner's continuity function lets you determine if there is
DC continuity between two un-powered wires.
WCaution
Before connecting the toner to unknown wires in
continuity mode, use the polarity mode to verify that
the wires are not powered. Connecting to powered
wires in continuity mode can damage the toner.
To check for DC continuity between two wires, do the following:
1
Connect the PRO3000 toner's red lead to one of the wires and
connect its black lead to the other wire.
2
Put the slide switch in the CONT position. If there is DC continuity
between the two wires, the continuity LED is red. The brighter
the LED, the lower the resistance between the two wires. The
toner indicates continuity up to 10 kΩ.
Using the RJ11 Modular Plug
The PRO3000 toner has an RJ11 phone plug, which you can use
instead of the clip leads when the pair of wires you are testing is
terminated with an RJ11 jack. The RJ11 plug is directly connected to
the toner's red and black clip leads. The plug's green wire (pin 4 of
the plug) is connected to the black clip lead; the plug's red wire (pin
3 of the plug) is connected to the red clip lead. You can use the RJ11
plug in any of the unit's operating modes.
