Features

  • Frequency response range is as wide as DC to 500 kHz, suitable for high-speed phenomena such as impulse wave.
  • Strain amplifier mode provides a range of 100μm/m.
  • Noise referred to input is low despite the wide bandwidth and high gain capabilities.
  • Balance adjustment is possible up to ±10000μm/m (equivalent to a resistance deviation of 2%).
  • RANGE, L.P.F., VERN and BAL settings are saved in nonvolatile memory.
  • User registration function improves the measurement accuracy. such as ;
    1) With CDV-700A, the cable resistance compensation function ensures the same measurement accuracy as ensured by remote sensing.
    2) With CDA-700A, other than 120 Ω or 350Ω .
  • Output of 4 to 20 mA is option.
  • Digital indicator and bar graph are provided.
  • Powerful low-pass filter provides the attenuation characteristic of -24 dB / oct.
  • Key lock function prevents maloperation of balance, range, vernier and low-pass filter switches.
