Polarity can often aid the user when identify-
ing a target from non-targets as the polarity
may flip from positive to negative
AUTO NULL
In environments with a persistent magnetic
signal, such as along a chain link fence or a
metal building wall, the Auto Null feature allows
the locator be re-zeroed to eliminate the read-
ings from that persistent magnetic signal.
While in the persistent magnetic field (but a -
way from the objects that you are trying to lo-
cate), press the AUTO NULL button. The
Absolute signal strength should reset to zero
(Figure 10) . Continue locate as before.
To turn off Auto Null and reset the unit to nor-
mal settings and sensitivity, cycle the power
OFF, then ON.
