Multi-meter Tests
Copper, VDSL2, ADSL2+ and IP Triple-Play Test Set 89
Multi-meter
Longitudinal Balance
The Long. Balance test allows you to
check that the longitudinal balance
ratio for the twisted pair complies with
applicable standards so as to reduce
the effects of common-mode voltage
to ground. The better the longitudinal
balance of the cable pair, the higher
the dB reading.
To start/stop the test:
Press to start/stop the test.
Test results are displayed on the screen as they are completed.
