Specially designed induction motor unmistakably indicates the phase sequence by direction of rotation or rotor disc.

  • The Lead Set is permanently connected to the instrument to save testing time and prevents errors in connecting
  • For ease and certainty in identifying connections, the test clips are permanently marked with letters A, B, and C, and the corresponding flexible leads and slip insulators are coded red, white, and blue.
  • Good visibility of the rotor movement is assured.
  • The black area of the aluminum rotor blacks out windows in phase sequence
