Model FL-20A Cable Fault Locator
Auto Frequency Select
When this setting is ON, the FL-20A will automatically find the opti
-
mum frequency at which to test. When the setting is OFF, it will test at
the Set Frequency, which may not give you correct results. The default
setting is ON.
Full Test
When this setting is ON, the equipment will first locate the distance of
the open from the blue probe, and then find its distance from the red
probe. A summary screen showing the distance of the fault from each
probe will display. The total of the two distances should equal the length
of the test cable. By pressing MORE, the operator may view the rated
accuracy of the results as well as a suggested cable area to remove. The
full report may be printed.
When the setting is OFF, the FL-20A performs only a partial test, find
-
ing the distance of the open from the blue probe and then pausing to
display a report. You may press BACK to terminate the test, but the
test’s accuracy is, at this point, unknown. If you instead press NEXT,
the FL-20A will then proceed to ind the distance of the short from the
red probe. A summary screen showing the open’s location from the red
and blue probes, as well as the rated accuracy of the test and the sug-
gested trim area, will display.
The default for Full Test is ON. Experienced operators working with a
particular cable type are sometimes confident that a partial test is accurate
and choose it to reduce test time. However, this is not recommended
without the advice of a Clinton technician.
Lock Test Frequency
When this setting is ON, the FL-20A will not prompt the user to enter a
test frequency before the Opens test. The default setting is ON.
Opens Start Frequency
This setting is found on Page 2 of the Opens Parameters menu. It is the
frequency applied during the Opens test. The default setting is 23.0 Hz.
Do not change this frequency without factory advice.
Hi-Pot Parameters
Access Hi-Pot parameters from the Settings menu.
Lock Hi-Pot Settings
When Lock Hi-Pot Settings is OFF, the user can change the values that
are entered in the Hi-Pot Parameters menu during a Hi-Pot test. When
Lock Hi-Pot Settings is ON, the operator cannot change the parameters
