Button
When pressed it stores the signal strength and sets the reference mode. The tone will beep more
rapidly as the STAFF detects a similar signal strength. Pressing the reference button again (after
a reference has been taken) will display the original reference reading for 2 seconds. Turn the
unit off and on to clear the reference.
DIRECTIONAL ARROW
After proper synchronization the arrows will direct the user to the fault. If the signal strength drops
completely off in the area between the ground rod and the fault, the arrows will not properly
display direction until the unit comes within range of the fault or ground rod.
SIGNAL STRENGTH
The Signal Strength is displayed in a value from 0 to 100. The closer to the ground rod and/or the
fault will result in the highest reading. The signal strength may drop completely off in the area
between the ground rod and the fault.
