The working characteristic of the Hall current sensor CSM025A was studied in the paper. The "modeling-deviation compensation" algorithm of adopting to compensate the deviation by the software way was proposed according to the deviation problem between actual working characteristic and ideal working characteristic of the output signal in current measurement. Experiments showed that the measurement result was accurate and the "modeling-deviation compensation" algorithm effect was good.
