PRO3000 Toner and Probe Users Guide
The SmartTone function works only if the toner's red lead is
connected to one of the wires of the pair and its black lead is
connected to the other wire of the pair.
SmartTone works on many types of wire pairs including twisted pair,
house wiring, and coax (the shield is one wire and the center
conductor is the other wire). SmartTone has a range of 2 miles (3.3
km). Using this function on wire runs greater than 2 miles in length
may cause misleading results.
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.
