Specification:Name: Electromagnetic Radiation DetectorSize: 132mm (length) × 69mm (width) × 29mm (high)Weight: 190 gramsReadings show: three and a half liquid crystal display, the largest reading 1999.Test bandwidth: 50Hz-2000MHzSampling time: about 0.4 secondsWorking voltage: 9VBattery Type: 6F22 9V Features:1. Simple operation, can quickly measure the home appliances, wires and industrial equipment around the electromagnetic radiation intensity.2. Easy to carry.3. The test band is wide. Numerical contrast is obvious, suitable for radiation effects of the measurement of the demonstration, and personal understanding of radiation.4. For environmental electromagnetic radiation testing: room, office, calculation5. Room, control room, cable, high voltage lines, monitors and other radiation source of the test the amount.6. Used for household appliances electromagnetic radiation measurement: computer, electricity.7. Video machines, photocopiers, fax machines, air conditioners, refrigerators and other radiation sources of the test analysis.8. Measured AC current radiation, direct electricity to meet the safety standards can not be measured. Measurement procedure:1. Press the power switch, to be measured to be measured electrical measurement.2. Holding the instrument slowly close to the object to be measured until it comes into contact with,The closer the object to be measured the greater the electromagnetic radiation value. 3. The measurement process to try to change the instrument angle, has reached the best test amount of effect.4. If the process of measuring the object closed in the power supply, the instrument reading should return to zero state unless there are other disturbances. About the battery:1. When the instrument test data becomes smaller or no alarm, please replace the battery in time.2. The instrument need to be stored to remove the battery. Package Included:1 x 1030SMP Power Booster
