Measurements up to +/- 1.000 aw
The new sensor of the LabSwift-aw is capable of measurements up to 1.00 aw
(100%rh). A built-in heating system protects the measuring cell from saturation
and therefore against destruction.
• The instrument must be switched on before a product sample is placed into
the measuring chamber.
• Always first remove the sample from the measuring chamber before the
instrument is switched off.
Note:
If possible always leave the LabSwift-aw switched ON. The integrated heating
system protects the sensor from saturation and the instrument is always ready
for the next measurement.
5.4. Function Principle of Stability Observation
The stability observation function, if activated, observes the changes in a
w
over a time unit. Stability will be shown when the change of the a
w
-value within
a selected time frame is less than < 0.001aw. The shortest time window
(„OBSTIME“) is 1 minute. This window can be increased up to 30 minutes or
a fix stability mode S, A and F can be selected. The optimal observation time
depends on the product sample and can be optimized stepwise.
