399,000円 （税込：438,900円）

  • The all-new PLZ-5WZ series allows for easily configured impedance measurements with dedicated impedance measurement software.
  • Impedance measurements are made during discharge, allowing for real-time measurement of impedance values from the DUT.
  • Capable of R, jX, θ, and Z measurements.
  • Measures AC frequency from 100 Hz – 10 kHz (seven fixed settings) and signal levels can be set arbitrarily.
  • Equipped with a voltage slope correction function that minimizes the effect of voltage slope during during battery discharge tests.
  • Zero adjustment function allows for increased accuracy during critical impedance measurements.
  • Measurement results and graphical information can be copied directly from the application software to programs like Excel.
