Call/block conductivity is significantly dependent on temperature. So that the measurements can be compared with each other, it must be temperature independent or it must be related to the same temperature at 20oC.
Compensation in the temperature is necessary because of the measured conductivity values where the measuring instrument is carried out by itself. The battery’s current temperature is entered into the measuring device. Measurement of the temperature which is of non-contact can be easily carried out with an infrared sensor or a thermal imaging camera.
