Model PTE-30-CH Portable Timer

This chronometer has been designed as an accessory to the injection instruments to test protective relays. Its function is to determine one of the most important parameters, the reaction of the delay time of a protective relay in relation to a trip condition. The time between activation / deactivation of any electrical contact can be measured.


  • Accuracy: ±0.01%.
  • Three selectable display modes:
    seconds / cycles / Frequency.
  • Resolution: 1ms.


  • Measures the trip time in protective relays.
  • Measures the time of contact operation.
  • Measures the duration of a single pulse.
