Vivax vLocPro Fault Finding Procedure
Before Proceeding:Targeted cable/conductor MUST be disconnected and
isolated from either “end” before accurate fault-locating can occur.
Transmitter
1. Plug in your Red/Black direct connect leads.
2. Connect
BLACK
lead to the ground stake, placed at a 90 degree right
angle or angled slightly behind faulted cable.
3. Connect
RED
lead to faulted cable (Be sure to ALWAYS follow company
safety procedures when working around potential energized conductors).
4. Turn transmitter ON.
5. Select a locating frequency, e.g., 8kHz / 33kHz / 65kHz, etc...
(NOTE: resistance measure mode cannot be accessed in FF mode)
WHEN ENTERING RESISTANCE MEASURING MODE (measuring fault
Ω
)
6. Press
i
button twice and then HOLD down to enter resistance measure
mode (Volts-Resistance will be on the screen). While HOLDING down the
i
button the screen should indicate a dashed-line moving across the
display. That is the internal DC circuit now measuring the resistance of the
target conductor. Repeat this step to make additional measurements.
(NOTE: Rule-Of-Thumb - The lower the resistance (~under 200k Ohms) the
larger the fault). If cable is good, HI-RESISTANCE may be displayed.
(
NOTE:
To proceed with fault locating, your RED lead must be attached to the
faulted cable/conductor.)
FOR CABLE LOCATING ONLY
7. Press
f
button to select the desired frequency (8kHz, 33kHz or 65kHz)
NOTE: However proceed to next step for fault locating.
FOR FAULT LOCATING
8. FF High must be selected for fault locating by pressing the
f
button until
FF High is selected on the display. This mode interacts with the A-Frame.
