Measure Pin Pairs:
Press the cable type button again to measure
the length of the first pin pair. The number(s) for the pair being mea-
sured will display in the screen (see Figure 14). Subsequent presses
of the cable type button will cycle through all the pairs and return to
the length reading for the entire cable when you have advanced past
the last pin pair. The following icons appear in the display screen:
▪
The cable type icon appears at the top of the screen.
▪
Length of pin pairs in units of feet or meters displays in lower
right corner of the screen.
▪
The “L” icon displays indicating you are in Length Mode.
▪
A bouncing ball activity indicator appears in the lower left
corner.
Note:
If the selected cable pair is shorted, “SHORT” will display for
the shorted pair and the length readout is dashes.
The number of wire pairs is dependent on the type of cable
you are testing. Data cables have 4 wire pairs and voice cables
have 3 pairs. If you are testing a video cable, you will receive
only 1 length measurement reading as a video cable has a
single wire pair.
