The minimum humidity is set to 0% H
ranges from 25% to 100% H
the minimum. See an example shown below or the graph Figure 8.2.
Numerical values are also equivalent for relative humidity Check the values by replacing vol %
H O with % RH

Setting example 1
If the minimum setting (for a 4 mA point) is 0% H
more than 25% H O.

Setting example 2
If the minimum setting (for a 4 mA point) is 26% H
at more than 44% H
