Running Inactive Pair Test and Viewing Results
Opens Meter
Opens Meter is a measured value for
each lead combination. The test
measures the capacitance of the loop
and Opens Length.
³
Opens Length is calculated from
the corresponding capacitance
and displayed in either meter or
feet, depending on the unit
selection in Regional Settings. If
the corresponding capacitance is < 0.2 nF or > 10 μF, N/A is displayed.
³
Opens Variance is the percentage difference between the capacitance
on T-G and R-G. If the capacitances on T-G or R-G are < 0.2 nF or
> 10 μF, N/A is displayed and the opens variance is considered a fail
status.
Load Coil
The Load Coil tab displays the number
of load coils detected in the line.
³
If only 1 or 2, Probable Filter
Detected is displayed.
³
Splitter Detected is displayed if
present.
Measured values from the load coil
detection test are shown in graphical
form.
