TX905 CABLEMATE
Cablemate comprises two components:
(a)
Probe
– used for tone search, cable pair identification and
to control the mode of the Oscillator unit.
(b)
Oscillator
– provides ‘pair identify’ signal to line. Also, on
receiving signals sent from the probe, the oscillator will
switch directly to the mode selected,
Pair Identify
,
Open
Circuit
,
Short Circuit
or
Exchange Connect
. The Red
LED indicates power is on and the battery is OK. At
switch-on the LED should light continuously for 2 seconds,
then flash once per second indicating that it is ON. If the
LED flashes rapidly at switch-on then the battery needs
replacing.
Note: Switch on always selects Pair Identify Mode.
PAIR IDENTIFICATION
(1) Connect the Blue and Red Oscillator leads to the line (Red
to Exchange and Blue to Customer – White Not Used). Switch
on by pressing the POWER button. Select the type of tone by
pressing the TONE button. The tone can be monitored using
the Probe.
(2) Move to far end of line and use Probe tip to identify cable
pair carrying the Oscillator Signal. The Probe sensitivity can be
selected by pressing the TONE button. The pair can be verified
by checking for a null (minimum signal) between the wires
carrying the tone. No null will be found if the pair is
unbalanced.
