The tester with acoustic signalization and measuring of the phases sequence. It is intended for indicative measurement of AC and DC voltage.

Technical parameters

  • AC and DC voltages from 6V to 400V with polarity indication
  • it indicates the voltage via LEDs: 6V, 12V, 24V, 48V, 110V, 230V, 400V. The last lighting LED determines the magnitude of this voltage
  • voltage tolerance: DC 10%, AC 15%
  • acoustic voltage indication is active for the voltage above 48V
  • the sequence of phases determination in 400V AC networks with grounded neutral or zero point
  • operating temperature: from -20°C to +40°C
  • protection: IP40
  • the maximum measurement time is 10 minutes
