Threshold Settings
button opens a new page
that allows you to set the capacitance balance
threshold for the test.
Result
displays a snapshot of the pass/fail
status,
Capacitance
and
Length
for each
selected wire pair.
Capacitive Balance
is
shown in

when
All Pairs
is selected.
Test Status
displays the current state of
measurement or an error message.
To select the parameter values:
1. Press the up/down arrow keys to highlight the
desired parameter.
2. Press the left/right arrow keys to view and
select the options.
OR
3. Press
on a value to open a list box of
options and use the navigation keys to scroll
through.
4. Press
to confirm the value.
Capacitance/Opens Threshold Settings
The
Threshold Settings
page allows you to set the
Capacitive Balance Threshold
parameters for the test
between 0 and 100 %. The threshold is a
programmable value you can use as an on-screen
indicator in each test when a measured value is too
high or too low. POTS and internet circuits should be
95 %, and higher speed broadband circuits 97 % or 98
% if possible.
Type
is the threshold limit for each pair: either
Maximum
or
Minimum
.
Enabled
is a flag to use the current threshold:
either
Yes
or
No
.
To select the threshold values:
1. Press the up/down arrow keys to highlight the
desired parameter.
2. Press the left/right arrow keys to view and
select the options.

9.8 Station Ground
The
Station Ground
test measures and displays the
resistance value and pass/fail status of the ground
resistance between the 6100-Gfast and the CO
(Central Office). A provisioned POTS circuit is required
for this test to work properly.
The test uses Tip (A), Ring (B), and Ground (Earth)
leads and measures isolation resistance between the
wires and to ground. Any ground should be < 25 0 for
safety reasons, and for high speed broadband (to
minimize noise and interference), the ground value
should < 5 0. If a ground value is > 25 0, it may not
provide a good path to ground and the current could
injure a person. For values between a few ohms and
25, there may be a differential with the premises
