  • 8 x 5.5 x 7 inch / 203 x 140 x 178 mm
  • Notes

  • This convertor, designed primarly for use with the Digitec range of DC voltmeters, enables AC potentials to be measured on any instrument operating from an input of 1 V DC. This model 1900 operates over the frequency range from 50 Hz to 25 kHz.
    Four input ranges: 0 to 1, 10, 100 and 500 V r.m.s. and the input impedance is 1 MΩ (100 kΩ on 1 V range).
    The DC output (1 V DC for 1, 10 and 100 V r.m.s, 0.5 V DC for 500 V r.m.s.) is available at low impedance (10 kΩ) and the reading time is 1 sec.
