ABSTRACT:
A multielement-sensor measuring device having a number of sensor elements is provided with a switching means, a measurement means, a memory data extraction means and an offset and gain compensation means. In adjustment of the device prior to actual measurement, the sensor elements are sequentially switched over to the measurement means which measures their output and produces and forwards to the memory for storage offset and gain values according to the variation in offset and gain among the sensor elements. During operation, the stored offset and gain values are extracted from the memory by the data extraction means and used to control the offset and gain compensation means, whereby the outputs from the sensor elements are compensated so as to be made free from variation in offset and gain.
