Magnetic Field Detection
1. Hold the meter in the area under test.

LED does not light when the ON/OFF button is pressed, replace the
battery.
1. Place the meter on a clean, flat, non-abrasive surface.
2. Loosen the rear bottom Phillips head screw to access the
battery compartment.
3. Lift the battery access door and replace the 9V battery observing
polarity.
4. Place the battery carefully in the compartment without crimping
the black and red battery connecting wire.
