Internal Resistance Meters
Here are the internal resistance values of NiMH cells measured by different analyzers. The values are compared to EM3610 that measures AC impedance at 1kHz.
The data were obtained by measuring dozens of NiMH cells - each with different resistance - with EM3610 first (used as X coordinate), then with the analyzer (used as Y coordinate). A smoothed bezier line was constructed from these (X,Y) data points. Finaly the desired values were read out from the bezier line into the table.
