The meter defaults to “EFHI”. Users can select different sensitivity levels according to the intensity of the measured electric field. Select "EFHI" of NCV when electric field is around 220V AC 50Hz/60Hz. Bring the NCV sensing end close to a charged electric field (socket, insulated wire, etc.). The LCD will display the segment "-" with beeps and red LED flashing. A s the intensity of the measured electric field increases, the more segments (----) display, the higher frequency of buzzer beeps and LED flashes. Select “EFLo” when the electric field is around 110V AC 50Hz/60Hz.Caution:Use the NCV sensing end to approach measured electric field, otherwise the measurement sensitivity will be affected. When the measured electric field voltage is over 100V A C, observe whether the conductor is insulated to avoid personal injury.9.5.2 Live/Neutral Wire Measurement (only UT204+) (Picture 6b)a. Select the LIVE function scale.b.
