      [1]Zero-based line of best fit, determined by the method of least squares
      [2]For an output range up to 10 V, the supply voltage of at least 26 V has to DC  , respectively. At low bias voltage of the sensor, no negative output range up to -10 V can be used.
      [3]Two identical sensors at a distance of 10cm mounted, see drawing # 65,310th For each channel, a separate calibration certificate is included.
