C2G 29404 Multifunction Cable Meter - Manual (Page 3)

CABLE LIBRARY SETUP
TheCableTool has one cable library for general electrical applications and
one for CATV installers. Pressing the Up/Down cursor key scrolls between the
two libraries. Pressing the Select function key makes that library of cable types
available for all length measurements.
POWER DOWN SETUP
The CableTool will automatically turn off after the time selected in the Power
Down Setup screen.
Settings available are five minutes, fifteen minutes, thirty minutes and on
(must be turned off manually). Press the Save function key to store the selected
setting.
POWER
Duration - The CableTool will typically provide 10-12 hours of operation from a set
of four AA alkaline batteries.
Auto Power Down
- The CableTool will automatically turn off after the time selected in
the Power Down Setup screen or will run continuously until manually turned off when
“ON” is selected for Power Down.
Low Battery - When the batteries are below the level required for the CableTool
to operate properly, a “LO BATT” message appears in the upper right hand corner
of the display.
SAFETY
Always disconnect the test leads from any cable before opening the battery
compartment cover.
OPERATION
Attach the test leads to the CableTool by inserting the safety banana plugs
into the banana jacks at the top of the unit. Turn the CableTool on by pressing the
“PWR” button. The startup screen is shown for a few seconds and then the Mode
Screen is displayed. Clip one test lead to each of two conductors of the cable to
be tested.
MODE SCREEN
When the Mode Screen is displayed, the CableTool immediately starts
measuring voltage and updates the reading
several times per second. If more than a 6-8
volts are present on the cable, do not conduct a
Length test or apply a Tone signal until the
circuit is de-energized. The CableTool can
withstand continuous input voltages of up to 250Vrms.
LENGTH SCREEN
Pressing the Length function key in the Mode Screen presents the Length
Screen. The CableTool automatically starts
measuring the distance to the fault (open or
short) using the NVP of the Default Cable (see
Default Cable Setup). Using the Up/Down
Cursor key, any of the eight user selected cable
types, the four custom cable types or a cable type from the prestored cable list
can be selected and the length is corrected for the corresponding NVP. The length
measurement is continuously updated.
When the NVP for a cable is known to be different than the displayed NVP,
the NVP can be changed by pressing the Select
function key to move the arrow to the NVP field
and then pressing the Up/Down cursor key to
modify the NVP. The NVP can also be modified
and stored in Cable List setup.
RECOMMENDATION: Before starting a job with a new spool or box of cable
that has a known length, make a length measurement with the CableTool to
determine if the prestored NVP for that cable type provides the correct length. This
is done by selecting a cable type that matches or is similar to the type of cable to
be tested, press the Select function key to move the arrow to the NVP field and
press the Up/Down Cursor key until the displayed length matches the known
length printed on the box or spool. The modified NVP will only be used while
making this length measurement, exiting the screen or turning off the power will
reset the NVP to the original value. To store the cable type with the modified NVP
see “Cable List Setup”. The prestored NVP is a typical value and adjusting the
NVP to the actual length will provide more accurate results. See “Understanding
NVP” for more information.
