Setup
Ultra, Fault Finder on Ultra Advanced

Transmitter must be running firmware v2 or greater.
1. De-energize and disconnect the cable at both ends.
Turning off a breaker is usually not enough to isolate the cable for fault finding.
2. Plug direct connect lead into transmitter.
3. Connect black lead of the transmitter to the ground stake and connect the red lead to
one end of the faulted cable.
4. Press the On/Off key to turn on fault transmitter.
5. Press and hold the Power Level key to enter menu.
6. Navigate down to Options menu and press Power Level key to select.
7. Navigate down to Fault Mode and press Power Level key to select.

If direct connect leads are not plugged in, Fault Mode will not appear in menu.
8. Select Enabled by pressing Power Level key.
9. Transmitter will return to main screen and be in fault mode.
If current is below 5 mA, increase power level until it shows 5 mA or transmitter is at highest
power level.
Readings > 100 k indicate no significant fault exists in the cable.
Readings < 50 k indicate a fault is likely.
Higher transmitter power levels give better readings. Try a higher power level to ensure the
cable is faulted.
After the transmitter is connected to the
cable, the impedance reading will help verify
that a fault exists on the cable.
While transmitter is in Fault Mode, the screen
will show:
• Current
• Impedance
• Voltage
• Power level 1
