5.4 Calibrating cable length
The cable characteristics parameter is now defined by the factory settings for the cable selected.
But cables are coming from different batches or manufacturers the characteristic variances will
be at up to 20%, to cause deviations in length measurement. To obtain more accurate
measurements, calibrate the tester to the specific cable under test. For proper calibration connect
the cable under test directly to the tester not through a patch cable. To calibrate the tester to the
currently selected cable, perform the following procedure.
1. Select cable type under test.
2. Connect a good cable of known length, >15 m and <100 meters, to the appropriate tester
connector.
3. Press SET key, then press
enter key,
until the display shown “ CAL CABLE ? ”.
4. Press ▼ ▲ key until “YES” is displayed, then press
enter key.
5. Press SET key, “to show cable length, press ▼ ▲ key to adjust the cable length to the exact
length.
6. Press
Key. These cable parameters are stored and will remain in memory even if the test
tool is turned off. All future measurements for this cable type are compared to these new
parameters, until another cable is selected or another calibration is performed.
