Performing a Shorts Test
Caution. DANGER!!!
It is imperative that only personnel trained in the dangers of high voltage
operate this equipment.
A stored charge in a test cable can kill!
A charge
can remain in a cable if the cable has not been properly discharged, even
when it is no longer attached to the FL-20A.
Discharge all conductors of the test cable prior to connecting to
the FL-20A to remove any stored charge from a previous operation.
A stored charge in the cable can be lethal.
Note: to determine the accuracy of the Shorts test that you can expect
on your test product, please refer to the chart entitled, “Cable Loop
Resistance Chart.”
1. Review the Shorts Parameters settings that have been entered
before proceeding with the test. They are found in the Settings
menu.
2.
Select the first conductor to be tested. Strip back by 1” and
insert the exposed conductor into the red test probe. Be sure
that insulation does not obstruct the connection between the
metal in the probe and the exposed conductor. Strip the other
end of the conductor and insert into the blue test probe.
3. Ground all untested conductors.
On one end of the test cable,
strip back all conductors not under test by 1”, carefully bunch
them together with the cable shield so that they make a good
connection with one another, and insert into the green ground
probe. Be sure that insulation does not obstruct the connec-
tion between the metal in the probe and the exposed conduc-
tors.
Do not attempt to bypass this safety procedure. Failure to
observe safety precautions can result in severe injury or death!
NOTE:
If conductors are too large to insert into the probes, see
the section entitled, “Testing Large Cables with the FL-20A.” It
is critical that conductors be connected properly. Poor connec-
tions can be dangerous to personnel; additionally, the FL-20A
graphics display may not function correctly due to noise.
4. At the main menu, press the Shorts button to begin a test for
high voltage shorts or metallic shorts. The screen will guide you
through the test.
5. Enter the maximum test voltage. (If the Lock Test Voltage set-
ting is ON, this screen will not be displayed.)
6. If the Printer Installed setting is ON, a screen will appear allow-
ing you to enter a reel description. The reel description will
appear on a printed test report, if one is desired.
