To start/stop a test:
1. Press the up/down left/right arrow keys on the
keypad to select the desired test icon.
2. Press
to confirm your selection.
3. The test will start automatically if the
Setup/Application Settings - Test Startup
Mode
is set to
Auto
. If not, press
Start/Stop
on the keypad.
9.2 Voltage
The
Voltage
test detects AC RMS and DC voltages in
the line and allows you to measure AC/DC voltages
and
Frequency
on A/B/E or T/R/G depending on the
selected
Standard
in
Setup/Application Settings
.
Voltage
tests are not meant, nor is the test set rated, to
measure electrical power circuits.
Continuous DC Page
With voltage measurements, you can detect crossed
battery, other foreign unwanted voltages, and even see
intermittent breaks or contact if the voltages fluctuate.
Most plant operators allow 3 or 4 volts of DC and/or AC
signal on working loops, although for higher speed
broadband circuits (ADSL2+ or VDSL2), even a few
volts indicate a small fault and some imbalance which
may affect the data rate. You would need to run
balance tests such as
Stressed Balance
,
VF/AC
Balance
, and/or short the far end and run
Resistive
Balance
to isolate small faults.
Larger foreign/unwanted voltages are a real problem
because they indicate a contact fault and add
unwanted noise affecting other signals (including
affecting test set signals). 48 to 52 volts would indicate
working POTS. If you have not already done so, press
and select
Pair Detective
to identify metallic faults
or even wetness.
The
Voltage
test defaults to the
Continuous DC
page
from the
Multimeter
menu. This function measures
each pair, displaying and updating results in real time,
until you stop the test. The last valid results then
remain displayed. If the DC value is fluctuating, it could
indicate the presence of moisture in a fault or possibly
a moving or swinging metallic fault, causing intermittent
breaks in the DC (such as POTS battery).
To view all lead combinations right away:
Press the
Snapshot
function key.
Continuous AC
and
Continuous DC
are run
synchronously. Press Start/Stop on the keypad to run
the test.
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
All Pairs
or
a single wire pair for measurement.
Termination Resistance
defines how much
resistance the tester uses to connect to the line
and measure voltages.
Threshold Settings
button opens a new page
that allows you to set the DC voltage
thresholds for each pair.
Result
displays a snapshot of the pass/fail
status and volts for each continuous DC pair.
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.
