Checking Polarity
To determine the polarity of a wire pair:
1
Put the toner's slide switch in the TONE position.
2
Connect the unit's red lead to one of the wires, and connect the black lead
to the other wire.
•
If the polarity LED is green, the toner's red lead is more negative than its
black lead.
•
If the polarity LED is red, the toner's red lead is more positive than its black
lead.
•
If the polarity LED is off, there is no DC voltage on the line.
If you know which of the two wires of a telephone line is Tip and which is Ring,
you can determine if the 48 V Central Office Battery is connected in its standard
manner by doing the following:
1
Connect the toner's red wire to Ring of the telephone line.
2
Connect the toner's black wire to Tip of the telephone line.
•
If the polarity LED is green, the CO battery is connected normally.
•
If the polarity LED is red, the CO battery is connected reverse from
normal.
Checking Continuity
The P 3000 toner's continuity function lets you determine if there is DC
RO
continuity between two un-powered wires.
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 P 3000 toner's red lead to one of the wires and connect its
RO
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 P 3000 toner has an RJ11 phone plug, which you can use instead of the
RO
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.
In-House Communications (Talk Battery)
Two P 3000 toners can power two telephone test sets on a pair of dry wires
RO
(Figure 5). This lets two people communicate on up to 1 mile (1.6 km) or more of
a dry wire pair.
To use the talk battery:
1
Connect the two toners in series by clipping the red lead of one of the
toners to the black lead of the other toner.
2
Connect one of the toner's free leads to one of the wires of the pair you
want to talk over.
3
Connect the other toner's free lead to one of the leads of your test
telephone.
4
Connect the test telephone's free lead to the other wire of the pair you
want to talk over.
5
Put the slide switch on both toners into the CONT position.
6
Have the person at the other end of the wire pair connect his test
telephone to the wire pair.
7
Put both test telephones in talk mode then begin your conversation.
