Operating Instructions
CAUTION: Read, understand and follow Safety Rules and Operating Instructions in this manual before
using this product.
WARNING: Risk of Electrocution. Before use, always test the Magnet Detector on a known live circuit
to verify proper operation
WARNING: Risk of Electrocution. Keep hands and fingers on the body of the probe and away from
the probe tip.
1. Press and hold the test switch (3) and approach the testing area slowly with the probe tip (1).
2. When a magnetic field is sensed by the MD10, the blue probe light (2) will illuminate. Solid light in
dicates a strong field; flickering light indicates a weak field.
3. To switch ON the flashlight (7), press and hold the flashlight switch (6). Release the button to switc
h the flashlight OFF. If the flashlight does not switch ON please check the batteries. The battery co
mpartment is located on the rear of the MD10 (8).
NOTE: The detector is designed with high sensitivity. Static electricity, stray magnetic fields, or other
sources of energy may randomly trip the sensor. This is normal operation. Strong fields will yield a
fixed indication.
NOTE: It is not necessary to unscrew the test object from its mounting on the equipment in order to
carry out a test; a magnetic coil can even be tested through its protective covering.
