SPX RADIODETECTION 6100-Cu Operation Manual page 75

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.

6100-Cu Multifunction Copper Tester Operation Manual
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
range selected. (A manual control TDR is
available in the TDR sub-menu from the
Copper Main menu).
