PRECISE MEASUREMENT The built-in electromagnetic radiation sensor displays the radiation value on the clear LCD digital display after processing by a control microchip. It can test magnetic field radiation with optional units mGT and the electric field with unit Vm. However, this EMF meter cannot test the RF value.Electric field Range 1Vm-1999Vm,Alarm threshold 40Vm.Magnetic field Range0.01T-99.99T 0.1 mG - 999.99 mG,Alarm threshold 0.4T 4mG.. SOUND-LIGHT ALARMWhen the testing result exceeds the value 0.4T 4mG or 40Vm, the screen will turn red, the indicator will flash, and the buzzer will sound an alarm. If you are testing in quiet areas, you can close the buzzer first to avoid disturbing others.. MULTIFUNCTIONThe meter can test average or peak value Maximum reading and hold the data for a view with a single key. Please make sure to confirm whether the hold key is pressed when measuring again. If H is displayed on the screen, cancel first and then measure again. The large backlit LCD provides clear viewing. The meter has an auto power-off feature after 5 minutes without operation..
