Due to the possible electromagnetic fiel dinterference in the environment, the displaymay show a small value after powering on. This is not the malfunction of the tester.

2. Making Measurements

Hold the tester in hand with the sensing area of the tester slowly approaching the electromagnetic radiation source to be tested (refer to Figure 3). The testing value and the indicator bar(s) show up to indicate the measured radiation intensity.

Note:

The radiation intensity increases as the tester gets closer to a radiation source. The higher the measured radiation intensity, the more indicator bars are displayed and the higher the testing value. When the measured radiation value exceeds the tester's alarm threshold (EF>40V/m, MF>0.4μT, RF>10mW/m2), the warning icon will appear on the display to show that the current radiation level is high. If the audible alarm function is enabled, the buzzer will sound.

Note:

1. Default electric field ( EF ) measurement mode after power-on, and short press the " MODE " button to switch the measurement mode.

2. Try different angles approaching the radiation source while making measurements. The highest radiation intensity indicated by the tester is the most accurate measurement result.
