Using Loop Testing
The FaultChaser can run a continuous test on a connected cable allowing you
accurately measure long cables susceptible to signal loss. Loop testing offers ease of
use by enabling you to test multiple cables without repeatedly pressing the TEST button.
1.
Press the POWER button to turn the unit ON.
2.
Verify the unit is set to the desired unit of measurement (feet or meters). To
change the unit of measurement, press and hold down the MEM and CAL buttons for
two seconds.
3.
Select the memory storage location (M1 or M2) that contains the NVP value for
the type of cable you are testing.
Note: Refer to the Using Memory Storage section for instructions on adjusting the NVP value.
4.
Press and hold down the TEST button for two seconds to run a continuous test.
The following values and icons appear in the LCD display screen (see Figure 10):
•
The “LOOP” icon flashes once in the upper right corner to demonstrate the unit is set to continuous
testing.
•
The measured cable length replaces the “LOOP” icon and flashes to indicate test activity. The
length flashes for the duration of a test.
•
The selected storage location (M1 or M2) and its respective NVP value appear in the lower left
corner.
•
The adjustment indicator icon displays to the left of the NVP value.
•
The cable fault (Open or Short) displays.
