Check and calibration
6.2.1 General information
The check/calibration can be carried out on the following devices:
On the IQ S
(see section 6.2.2 F
and section 6.2.3 C
on an IDS meter
(see operating manual of the meter)
Details of the check or calibration may vary depending on the device
selected.

The FDO
925 is factory calibrated. The measuring characteristics of the sensor
cap remain stable for the specified service life. Thus, calibration is usually not
required.
A check or calibration can be useful in the following special cases:
If the measured values appear to be implausible and it is assumed that the
service life of the sensor cap is over
Routinely within the framework of the company quality assurance
A check/calibration is carried out in water vapor-saturated air (test and storage

Check).
With the calibration procedure, the relative slope of the sensor is determined.
The calibration is evaluated based on the relative slope and the intensity
(successful <-> unsuccessful).
