Toner and Probe Users Guide
Checking Polarity
To determine the polarity of a wire pair:
Put the toner's slide switch in the TONE position.
1
Connect the unit's red lead to one of the wires, and connect the
2
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:
Connect the toner's red wire to Ring of the telephone line.
1
Connect the toner's black wire to Tip of the telephone line.
2

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
RO
DC continuity between two un-powered wires.
W
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:
Connect the P 3000 toner's red lead to one of the wires and
1 RO
connect its black lead to the other wire.
Put the slide switch in the CONT position. If there is DC continuity
2
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 k.
Using the RJ11 Modular Plug
The P 3000 toner has an RJ11 phone plug, which you can use instead
RO
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.
In-House Communications (Talk Battery)
Two P 3000 toners can power two telephone test sets on a pair of
RO
dry wires (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:
Connect the two toners in series by clipping the red lead of one of
1
the toners to the black lead of the other toner.
Connect one of the toner's free leads to one of the wires of the
2
pair you want to talk over.
Connect the other toner's free lead to one of the leads of your
3
test telephone.
4
Caution
Connect the test telephone's free lead to the other wire of the
4
pair you want to talk over.
Put the slide switch on both toners into the CONT position.
5
Have the person at the other end of the wire pair connect his test
6
telephone to the wire pair.
Put both test telephones in talk mode then begin your
7
conversation.

Cleaning
For general cleaning, wipe the case using a soft cloth slightly
dampened with water or a non-abrasive mild cleaning solution that
does not damage plastics.
W
Do not use CRC Cable Clean
aromatic hydrocarbons on the case. Doing so will damage the
plastic.
