Continuity Test
•
Connect the red test lead to one wire and the black lead to the other wire of the
telephone line being tested.
•
On the Tone Generator put the function switch to CONTINUITY position.
•
If the CONTINUITY LED turns green
if there is an electrical path between
the connection points.
•
The tester indicates continuity up to
10kΩ.
•
The LED is brighter on low resistance
and less bright on higher resistance.
Supplying Talk Power
•
Insert the RJ11 plug into the telephone socket and put the function switch to
CONTINUITY mode to supply talk power.
Note:
the tone generator has an RJ11 phone plug which can be used instead of the
clip test leads when the pair of wires being tested is terminated in an RJ11 jack. This
can be used in any operating mode.
