Analog Bar-Graph Signal Indicator - the bar graph corresponds
directly to audio frequency by expanding outward from the
center “diamond” as the signal increases due to magnetic
metals.
Low Battery Indicator - Although not visible under normal con-
ditions the LCD will display a flashing “Low Battery” warning
when the batteries fall below a predetermined voltage. This
alerts you to replace the batteries soon. Several hours of bat-
tery life remains. However, in cold temperatures this usable
time may be shorter.
Power Line Indicator Feature
The electro-magnetic fields
radiated from buried or over-
head power lines are picked
up by the new sensitive elec-
tronic circuitry and internally
transformed into a visually
flashing indicator in the dis-
play window as shown:
The distance or detection
range from the cables where
the locator responds de-
pends on the energy being carried by the electrical conduc-
tors. The higher the energy, the greater the distance the loca-
tor will respond to it. If the cables are dead (no electrical con-
nection or energy transfer), then no visual indication will ap-
pear.
When the locator is turned ON, this feature is activated
immediately. This feature only responds to 50 or 60Hz power
line frequencies and not to telephone or TV cables. This fea-
ture is intended as an aid only and not to be used for lo-
cating or pinpointing electrical cables.
The magnetic detection operation and performance of the
magnetic locator are completely independent from the power
line indicator feature.
