ELF MeterThis EMF meter, known as the ELF meter, is known for quick and easy use at an very affordable price. Three LED lights which are easy to see in the dark indicate field strength.
Three LED lights signal field strength:
- Green 'ON' indicator: 0 - 2.5 mG ("little or no activity")
- Yellow: 2.5 - 7 mG ("moderate activity")
- Red: 8 or more mG ("high activity")
DIRECTIONSTo replace battery you will have to remove the back battery cover with 3 screws on the back. This will expose the 9V battery harness. Plug in a new battery, place in the cradle and re-assemble the back cover using the same 3 screws. Turn the unit on using the side ON/OFF switch.
This is my first EMF reader and I can't wait to use it! It arrived promptly and the customer service from GhostStop was great!
