METER FUNCTIONS
The TriTone Transceiver includes metering to allow the user to assess the
preliminary status of cable pairs.
Any indications of problems on the pair should be further investigated following
local practice.
VDC shows the DC voltage on the pairs and helps identify POTS, Special Circuits,
and DC faults such as foreign voltage.
VAC is used to assess noise on the pair. Noise is a common cause of voice and data
problems on a pair.
TDR shows the approximate length of open pairs and estimates distance to
resistive faults.
6.1
THREE TERMINAL METERING
The TriTone Transceiver DC and AC meters use a three terminal meter display.
This allows the TriTone Transceiver to display the measurements Tip to Ring, Tip
to Ground, and Ring to Ground simultaneously.
6.2
METER CONNECTIONS
The pair clips and the ground cord are used for DC and AC meter functions.
Connect the Green ground, Black (Tip), and Red (Ring) clips as you would for
sending tone.
