Model FL-20A Cable Fault Locator
Testing for Metallic Shorts Accuracy
To perform a Metallic Shorts Test, connect the probes to the Shorts terminals
as shown. Note the Green ground probe connects to the terminal labeled
“METALLIC SHORTS”. Run the Shorts Test on the cable fault locator at a
voltage of at least 1kV. We expect a result where the fault is 90% (or within
our margin of accuracy) from the blue side and 10% from the Red side. These
two results should total approximately 100%.
Testing for High Voltage Shorts Accuracy
For running a High Voltage Shorts Test, connect the probes to the Shorts
terminals as shown. Note the Green ground probe connects to the terminal
labeled “HIGH VOLTAGE SHORTS”. Run the Shorts Test on the cable
fault locator at a voltage of at least 8kV. We would expect a result where the
fault is 90% (or within our margin of accuracy) from the blue side and 10%
from the Red side. These two results should total approximately 100%.
