Resistive Fault Location (RFL) Test
Two Methods for Performing an RFL Test
RFL Test Single Pair Method (CAT 500 H/W) (continued)
Multi-Gauge Cable Span:
Technicians use the multi-gauge setup option to accurately measure a pair con-
taining sections of multiple gauges and/or cable with diff erent temperatures (buried and aerial). Because these
variables aff ect the resistance of the pair, the accuracy of the conversion is also aff ected. Th
erefore, the HST-
3000 must be confi gured to closely refl ect the true conditions of the pair. Th
e larger the error for cable gauge
or temperature is, the greater the impact these variables will have on the accuracy of the measurements.
To prevent any discrepancies that can cause a distance conversion to be inaccurate, enter the gauge, tempera-
ture, and distance for each section of cable by following these steps:
1. Press
the
Conf gure
action key
2. Press
the
Display
soft key
3. Select
“
Display Multi-Cable Setup
”
To add new sections of cable, press the
Add
soft key. When prompted, enter the gauge, temperature, and
length of the cable section. If the
Delete
soft key is pressed, it will delete the last section listed. After entering
each section of cable is entered, press the
Home
or
Cancel
button. To enter an unknown value for tempera-
ture or distance on one section of cable, type #; the HST will calculate the value of this missing fi eld.
4. Press the Actions soft key and select “
Use Multi Gauge Cable Span
”
