Multimeter Tests
Copper and G.fast/VDSL2/ADSL2+ Multi-play Test Set

Isolation
Continuous
The Continuous function measures each pair,
displaying and updating results in
real time
, until you
stop the test. The last valid results then remain
displayed. Remember that the continuous application
of a higher voltage tends to dry up moisture in faults,
making it seem as if they have disappeared; but only
the moisture is gone and will likely reappear another
time.
Note: The test should be run with an open circuit at the far
end.
Note:
If UFED Control option is enabled, due to its limitation, the Continuous
function will act the same as the test in Snapshot mode and terminate
after the Soak Time period expires.

Current Group
is the current test group name, for example
Multimeter .

Current Test
displays the test being measured. Here you can switch to
another test from the given list. However, this action will terminate the
ongoing measurement test.

Selected Pair allows you to select a single wire pair for measurement.

Soak Voltage
allows you to apply a voltage value to the pair(s)
currently under test. Select a value from the list or User Defined to
enter your own value. If your unit has the HIVOLT (high voltage)
software option configured, the
Soak Voltage parameter values are
extended up to 500 V max.
Note: Since Soak Voltage is inherited in other tests that use the Isolation test, the
HIVOLT software option also applies to the following tests: Pair Detective ,
User Auto Test .
