Key Features:

  • 2000mS 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. The 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.
