- Outline
+ The impedance meter KFM2030 is intended to enable the impedance characteristics of a fuel cell to be measured easily through the use of the AC impedance measurement method.
+ Using the application software that comes with it, the meter can obtain impedance values at different frequencies by means of AC impedance measurement and display the obtained values in a Cole-Cole plot. With a low-power DC load (60 W) built in it, KFM2030 supports fuel cell load testing at up to 20 V, at up to 30 A.
- Impedance of cells of up to 20V can be measured in the range of 10 mHz to 10 kHz. (The cell voltage can be read back as well in the 0 V-20 V range.)
- Two constant current modes ranges for the load rating: 30 A and 5 A
- Load current setting resolutions of 1 mA (30 A range) and 0.1 mA (5 A range) are available, with maximum power consumption of 60 W.
- Undervoltage protection, overvoltage protection, overpower protection, overheat protection, overcurrent protection, and line cut detection are supported.
- The backlit LCD offers enhanced visibility.
- Four types of measurement value can be chosen for display freely from R, X, | Z |, θ , V, and I.
- Equipped with GPIB, RS-232C and USB interfaces as standard.
- Impedance measurements can be made in the range of 10 mHz to 10 kHz as well on both primary and secondary cells.
