The battery tester operates in accordance with the well-tried four conductor measuring method and combines the functionality of a testing device and an analyzer. The measuring device supports exact determination of the real (ohmic component) and imaginary component (capacitive or inductive component) of batteries with the impedance measurement and the spectral (complex) impedance measurement. The measurement results are displayed in a locus curve in accordance with the real component and the imaginary component. The respective battery voltage is also recorded during these measurements.
With the aid of various approximation functions, important model parameters such as serial inductance, series and parallel resistance and double layer capacitance can be determined and evaluated using the intuitively operated PC software. All measurements can be stored or displayed using log viewers and analyzed by means of gap-free history examination.
The capacitance measurement is determined via discharging with a constant current until the end point voltage is reached. You can choose between partial or complete discharging of the battery. A temperature measurement can be carried out on the test object using external Pt1000 measuring sensors. The battery tester is supplied via with 5 VDC via a galvanically isolated USB interface and there does not require an additional power supply.
