The EMF tester can be used to measurement the magnitude of electromagnetic field radiation generated by power line, compute monitor, TV set, video/audio machine, microwave oven, or many other similar devices.
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.
