Humidity (amount-of-moisture-content) setting range
The minimum humidity is set to 0% H
2
O or ranges from 26 to 100% H
2
O. The maxi-
mum 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.
Setting example 1
If the setting (for a 4 mA current) 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 setting (for a 4 mA current) is 26% H
2
O, you must set the maximum (20 mA)
point at more than 44% H
2
O, (263 0.8 + 23% H
2
O). (Numbers after the decimal
point are rounded up.)
