Turning on the Tester
Turn the tester on by pressing the
ON/AUTOTEST
key.
The tester performs a self test each time it is turned on.
During the self test, the tester displays
8888
.
Automatic Power-Down
To save battery power, the tester automatically turns
off after five minutes if it is not connected to anything,
or one hour after you connect to a cable. Also, if the
ON/AUTOTEST
key is held down for more than 20
seconds, the tester turns off. This prevents battery drain
if an object accidentally presses the key.
Testing Cables
Caution
When testing telephone cables, connect the
tester only to non-working circuits. If
accidentally connected to a working XDSL or
T1 circuit, the tester can cause a service
outage.
To test a cable, attach the test lead clips to a pair of
wires at one end of the cable you are testing.
The tester shows the distance to the nearest fault it
finds. Table 1 describes the tester’s display and beeper
indications.
Note
Length measurements do not include the
length of the test leads.
