Page 7: Voltage Measurement
Wiring test Notes: The analyzer can't detect 1. Circuit voltage, i.e. the voltage between two live lines; 2. Combined fault; 3. Reverse connection of earth line and neutral line. The wiring test result will be shown immediately Voltage measurement after the analyzer is plugged to the socket under The normal measured value of phase voltage is test. - Page 9 Voltage drop (V ) measurement If the voltage drop exceeds 5%, and during the measurement made near the switchboard, the Dummy load shall be used in the circuit to reading drops constantly and no obvious change measure the load phase voltage and then calculate is found between the two sockets, it indicates that the voltage drop.
