   Operation Instruction

1. Turn on the tester. Place the tester at desired position or near the object to be tested, point the sensor to this device.
Note: The nearer the sensor approaches the device, the higher the electromagnetic field radiation level may be.

2. Change the angle between the tester and the device under test until the max. reading is obtained. This max. reading is the measurement result, reading's unit is milligauss (mG). Turn off the tester.
Note: Due to the disturbance of the electromagnetic field in the environment, the tester may show a reading on the display before you perform measurement.
Do not expose yourself to electromagnetic field radiation for a long time.


EM556 Measurement Range: 0.1 ~ 199.9mG(milligauss) / 0.01μT~ 19.99μT
(1mG=0.1μT )

Different country has a different standard.
According to the standard of the Europe and America, the EMF value is not harmful for human body when it is lower 0. 2μT.
Maybe you can search google and find a more accurate standard value.

Operation tip: Don't forget to press the TEST button. And please make sure: the angle between the top of the tester and the object tested needs to be 90 °perpendicular.
