TESTING A CABLE

•

The “Ready” icon will appear and a measurement will be taken of the cable

length automatically. This measurement is updated every ﬁ ve seconds.

•

If the cable is shorted, the “Short” icon is displayed.

USER MODE

•

If “User” Mode is selected the “Ready” icon will display along with

readings for pF (capacitance per foot) and a length measurement.

•

The

downwards. Holding the

DOWN

to be changed more quickly.

•

With a cable sample of known length, a user can adjust the pF

constant until the indicated length measurement matches the actual

cable length. Then this setting can be used to measure other cables

of the same type. This pF value is saved until changed again in “User”

Mode or battery replacement resets the unit.

•

The distance for this mode is updated every second.

•

TIP: Using a longer calibration cable will reduce the error in

subsequent tests.
