The high voltage indicator which the display method is brightness using together with sensor can indicate the electriferous state of the voltage circuitry .
DXN9-C use together with the indicator which the hole distance of the power-check terminal is 14mm or 19mm, which can indicate the electriferous state .
Phase comparator DXN-C use together with the high voltage indicator can indicate the electriferous state of the connection circuitry and check the phase sequence of the electric device .
Power-check: phase comparator insert into the earthing or the other terminals of the high voltage device .
Phase-check: phase comparator insert into the same phase power-check terminal of the two high voltage device , if the Led is brightness, it shows that the testing phase have power supply.
