Impedance measurement function(factory option)
PLZ-5WZ Series
PLZ-5WZ
399,000円 – 735,000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.
