Using Length Mode
Length Mode is used to measure the length of entire cables and its pin
pairs and allows you to view and adjust the length constant value for
video, data, and voice cables.
Measure Cable Length
The CableMaster measures the entire length of a cable as well as the
length of individual wire pairs.
Note:
Using coax or data remotes while measuring length will add
one to two feet to the length reading due to internal stray
capacitance.
If a cable’s capacitance is too large, dashes will display for the
length.
1. Make sure the CableMaster is turned OFF.
2. Insert the cable plug into the corresponding receiver on the main tes-
ter (RJ11 jack for voice cables, RJ45 jack for data cables, F-Connector
for video cables).
3. Press the LENGTH/TONE button to enter Length Mode. The following
icons appear in the display screen (see Figure 13).
▪
An “L” icon appears in the right side of the screen.
▪
Cable length in units of feet or meters displays in the bottom
of the screen.
▪
The connector type last selected (voice, data, or video)
displays in the top of the screen.
▪
An “o” symbol bounces in the lower left corner of the screen
to indicate activity.
