4.7 Calibration data
Each calibration of IQ sensors that are able to be calibrated causes an
entry to be made in the log book. Log book entries contain the following
information:

Calibration date

Calibration successful or not successful.
The detailed calibration data of the last calibrations are integrated in the
Calibration history of selected sensor
overview.
4.7.1 Calibration entries in the log book
The date and time of a calibration are entered in the log book. The
respective message text contains an indication as to whether a calibra
-
tion was successful or not. The values determined with calibration can
be viewed in the calibration history (see section 4.7.2).
Details on calibration are given in the operating manual for
the IQ sensor.
All calibration data are stored in the IQ sensor. In order to
view the calibration data of an IQ sensor, the IQ sensor
must be connected to the IQ S
ENSOR
