OPERATION
The next example will demonstrate a 3 point humidity adjustment.
In this example 30, 50 and 70%RH , but any other point is also possible.
(%RH and Temperature adjustment are done in the same way)

Adjustment Point.
1.
Place the HS3-Probe together with a reference in a controlled and stable
environment of 30%RH.
2.
Check the readings of the HS3-probe and the reference.
•
The Humidity reference is reading 30.8%RH.
•
The HS3-probe reads 28.0%RH.

Probe readings prior to adjustment
3.
Find the nearest point in the RH Adjustment table (in this example 30)
and change it into the measured reference value. (in this example 30.8).
4.
Subtract the Humidity value of the HS3-probe from the reference value
(30.8 - 28.0 = 2.8).
5.
Add the outcome to the reference value (30.8 + 2.8 = 33.6).
6.
Enter this value in the corresponding
