    Key Features:

    • 2000 ms readout for testing latest delay action breakers
    • Fully programmed operation
    • Accurate digital read out of tripping time
    • Two LED’s lamps give quick check for correct wiring
    • Operates from mains supply. No need for batteries
    • Compact, lightweight and simple to operate
    • Zero cross circuitry permits testing at 0° and 180° portion of
      sine wave. At these two tests minimum (best) and maximum
      (worst) trip times will be displayed
    • Data hold function to freeze the digital trip time display allows
      for easy readout and eliminates the possibility of reading error

    The DT-904 is the Basic test Equipment an Electrician cannot do without. DT-904 is a Dual Function Test Instrument utilized to Verify electrical Wiring Connections and the Functioning of Earth leakage / Residual current detectors by forcing the ELCB / RCD to trip.

    This verifies that the protection device open the mains power supply circuit when a current higher than a certain amplitude circulate into the ground/earth wire. This ensures the Electrical installation meet safety regulation requirements.
