Preparing the Test Tool for Use
7
Note
Cables not wired according to the predefined
cable list cause the test tool to detect failures.
However, the test tool will determine the cable’s
length and display the actual cable wiring with
the wire map function. It may be possible to use
the test function by making an adapter that
causes the cable to appear to be properly wired
to the test tool.
To set up the test tool for the desired cable, perform the
following:
Note
The number of steps necessary to select a cable
definition will depend on the type of cable selected.
1. Turn the test tool on by selecting TEST, LENGTH, or
WIRE MAP.
2. Press A.
3. Press C or D until the desired cable type is
displayed, then press E.
4. Press Cor D until the desired wiring standard is
displayed, then press E.
5. Press C or Duntil the desired category is
displayed, then press E.
6. Press C or D until the desired wire size is
displayed.
Note
You can check the cable selection at any time
other than during the setup mode by pressing
the
E
key.
The cable characteristics are now defined by the factory
settings for the cable selected. However, cables coming
from different batches or manufacturers can have
characteristic variances of up to 20 %, causing deviations
in length measurements. To obtain more accurate
measurements, calibrate the test tool to the specific cable
under test.
Calibrating the Test Tool to the Cable
When calibrating the test tool to a specific cable, the
cable should be at least 100 feet (30 m) long and of the
same type and category as the cable under test.
Calibrating with cables longer than 100 feet (30 m) will
improve length measurement accuracy. During the
calibration process, if the cable is found to be defective or
if the cable is less than 50 feet (15 m), “BAD CABLE” is
displayed and the calibration process is terminated.
