Pinpoint The Fault - Amprobe A-5000 Mode D'emploi

2. Monitor bar-graph LCD display for arrow direction. If the arrow points AWAY from the ground rod, there is a fault.
3. If the arrow points TOWARDS the ground rod, there is no fault, and grounds and connections need to be rechecked.
4. The number of bars on the LCD indicates the potential gradient associated with the fault at the synchronization location.
5. The number of bars will decrease when you move away from the synchronization location and will increase when you get
closer to the targeted fault. See Figure 3-4

Pinpoint the Fault

1. Keep the A-5000 parallel to the target cable.
2. Insert the A-5000 firmly in the ground every 10' – 20' (3 -6 m). Follow the arrow.
3. When the arrow changes direction, the fault may have been reached or passed.
Look at the number of bars activated as well as the "Actual" LCD reading and compare them to number of bars you
read at synchronization point as well as the "Reference" LCD reading. If the number of bars or the "Actual" and
"Reference" readings are similar to the number of bars at synchronization point, you have located the main fault.
