Multimeter
The
Multimeter
page displays the raw values used by
Pair Detective
to identify a fault on the summary
screen. Read-only results and the
P/F
(pass/fail) status
are shown for the following tests:
DC Voltage
displays the volts for each DC
Pair
.
DC Current
displays the
DC
current results for
T-R/A-B wire
Pair
.
Capacitance/Opens
displays
Capacitance
and
Length
for each wire
Pair
as well as
Capacitive Balance
among
All Pairs
in %.
Isolation
displays
Resistance
and a
Soak
Counter
for each wire Pair.
TDR
TDR
is included to help locate faults identified on the
summary screen, and runs every time
Pair Detective
runs. It remains running and allows you to control and
edit the
TDR
test. It runs continuously after the one-
minute test cycle is completed using the setup
parameters from the initial cycle of the
Pair Detective
test. After saving the results, the
Pair Detective
results
will contain the
Estimated Length
value as found for
the initial cycle of the
Pair Detective
test. But you may
continue to use the
TDR
test to further locate faults on
the line.
The
TDR
test displays the line trace and is continuously
on and ready to use. It displays and updates results in
real time, in either
Portrait
or
Landscape Mode
(recommended), until you stop the test. The last valid
results then remain displayed.
Current Test
displays the test being
measured.
Range
allows you to set the range from the
given list.
Gain
allows you select the gain test parameter
from the given list.
The previous 2 parameters have 2 modes of
operation:
o
Auto
is the default mode upon loading
the test page.
TDR
automatically
optimizes the test parameters and
scans each band individually looking
for one
Largest Event
in each band (if
any).
Range
and
Gain
are updated to
reflect optimized TDR settings. Once
results are displayed, TDR switches to
manual mode. The test keeps running
until you press Start/Stop.
o
Manual
mode allows you set the test
parameters to be used as inputs for the
TDR measurements.
Note: If either of the above 2 test parameters are set to
Auto, respective parameter values will be
updated by TDR test.
Pulse Width
is a non-editable value that is
updated dependent on whether the parameters
are set to
Auto
or manual. The test set
automatically adjusts pulse width based on the
