Calibration
4.3.1 Overview
In the delivery condition, the sensor is precalibrated and ready to mea-
sure (see section 3.4.1).
There are two types of calibration that are included into the calculation
of the measured value at different points (see section 4.1):
User calibration (see section 4.3.2)
Zero adjustment
Sensor check/
An overview diagram of the calibration procedures can be found on
page 6 - 9.

We recommend to check the current user calibration against indepen-
dent comparison measurements if you suspect a basic change of the
characteristics of the test sample. If the comparison measurements
show clear deviations, these can be compensated by a user calibration.
