The Chroma 19311 battery tester checks the quality of the insulation between the positive and negative plates of lead-acid battery cells. For this purpose, a high-voltage current surge / pulse of up to 6 kV is applied before the electrolyte injection. The overvoltage tester has four connection measurements and a sampling rate of 200 MHz.
The Chroma 19311 offers 8 types of assessment: area, difference area, flutter, Laplacian, V1, V3, peak ratio and Δpeak%.
