No-trip earth loop impedance 5. Prospective earth fault current and touch voltage6. Voltage harmonics up to 50th7. THD% (Total harmonics distortion)Tests are selected by pressing the FUNC button. Sub-function features can be selected through the F1 and F2 buttons, for example for selecting the RCD type or displaying different harmonics. The instrument is powered through the line input, but with the supercap technology, the display will remain visible. Fully charged, the supercap will allow ~45 seconds of use after switch off from the line. This allows the user to remove the unit and read the displayed result. This is useful, should the socket be mounted in a hard to access location.4.1 Volt and socket testThis feature measures Voltage between phase and neutral and tests the socket wiring and polarity in accordance to local requirement.
