In the case of the Novasina AW SPRINT a distinction is made, in principle,
between two types of calibration:
– Routine re-calibration of individual humidity reference points
Individual humidity reference points can be (re-)calibrated at any
time with the appropriate humidity standards.
If the Novasina AW SPRINT is used throughout the full humidity
measurement range, but above 0.1aw, the unit should be calibrated at
all 6 points from 11 to 98%RH. If it is only used in one particular humidity
measurement range, calibration at 2 to 3 points covering the measure-
ment range used is sufficient. For very dry products, also the 6% point
should be calibrated, perhaps even 4%.
Important: To guarantee an accurate measurement, the instrument
must be calibrated at at least 2 humidity reference points, and for
accurate measurements across the whole measuring range at all
humidity reference points.
– Setup calibration (by service personnel only)
In order to carry out the basic calibration, the calibration values of all
the humidity reference points must first be deleted. The basic
calibration must be carried out whenever a new sensor is used, or
calibration can only be carried out with one humidity standard (in that
case always SAL-T75). The humidity standard SAL-T75 must be used
for the basic calibration.
