l Humidity (amount-of-moisture-content) and relative humidity setting range
The minimum humidity is set to 0% H
2
O or ranges from 26 to 100% H
2
O. The maximum humidity
ranges from 25% to 100% H
2
O, and must be greater than 0.8 times plus 23 the humidity set for
the minimum. See an example shown below or the graph Figure 8.2.
H

O with % RH
Setting example 1
If the minimum setting (for a 4 mA point) is 0% H
2
O, you must set the maximum (20 mA) point at
more than 25% H
2
O.
Setting example 2
If the minimum setting (for a 4 mA point) is 26% H
2
O, you must set the maximum (20 mA) point
at more than 44% H
2
O. (26 x 0.8 + 23 = 44 vol% H
2
O). (Numbers after the decimal point are
rounded up.
