MEASUREMENT OF CABLE LENGTH
The instrument measures the length of cables with RJ45 connectors of type UTP/STP, on
RJ11 cables and on coaxial cables (COAX) with F connector. Proceed as follows:
1. Switch on the instrument by pressing the key.
2. Enter the programming menu (see § 5.1.3) and select the numeric marker (values
between 0 and 9) to which the type and possible calibration of cable length are
associated (see § 5.5.1).
3. Connect the end of the cable to be tested to input connector RJ45, RJ11 or COAX
4. Connect the other end of the cable to be tested to connector RJ45, RJ11 or COAX of
remote unit #1
5. Press the
L/W
key to select the cable length measuring function
6. Press the
TEST/
key to measure length with reference to pair
“
1-2
”
for RJ45 and
RJ11 cables (see Fig. 14
–
left side) or for COAX cables (see Fig. 14
–
right side).

7. Press the arrow keys
or
to display the length of the remaining pairs
“
3-6
”
,
“
4-5
”
and
“
7-8
”
of the RJ45 cable being tested (pairs
“
3-6
”
and
“
4-5
”
for RJ11 cables).
5.5.1. Calibration of cable length
In order to obtain accurate measurements, it is possible to calibrate the instrument on the
specific cable being used. In order to perform calibration, connect the reference cable (with
an already known length) directly to the instrument without patch cables and follow this
procedure:
1. Switch on the instrument by pressing the key.
2. Press and hold the
L/W
key for 3s. The screen in Fig. 15 appears on the display.
