Turning On The Tester; Automatic Power-Down; Testing Cables - Fluke TS 90 User Manual

Turning on the Tester

Turn the tester on by pressing the ON/STANDBY button. The
tester performs a self test each time it is turned on. During
the self test, the tester displays 8.8.8.8.

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/STANDBY
button is held down for more than 20 seconds, the tester
turns off. This prevents battery drain should some object in
your tool box be leaning on the button.

Testing Cables

When testing telephone cables, connect only to
non-working circuits. If accidentally connected
to a working ADSL or hi-cap circuit, the tester
will cause an outage.
To test a cable, attach line cord clips to a pair of wires at one
end of the cable you are testing.
The tester displays the distance (in feet) to the closest fault it
finds. Table 1 describes the tester's display and beeper
indications.
