Sample record:
Note
If non-ID sensors are used, the sensor type and series number are not
output in the calibration record.
Calibration evaluation After calibrating, the meter automatically evaluates the calibration. The
zero point and slope are evaluated separately. The worse evaluation of
both is taken into account. The evaluation appears on the display and
in the calibration record.
