Figure 8.2 Max. and Min. Humidity Set Ranges
"Mixing ratio" setting range
l
The minimum mixing ratio is set to 0 kg/kg or ranges from 0.201 to 0.625 kg/kg. The maximum
"mixing ratio" setting ranges from 0.2 to 1.0 kg/kg, and must be greater than 1.3 times plus 0.187
the mixing ratio set for the minimum.
Setting example 1
If the setting (for a 4 mA current) is 0 kg/kg, you must set the maximum (20 mA) point at more
than 0.2 kg/kg.
Setting example 2
If the setting (for a 4 mA current) is 0.201 kg/kg, you must set the maximum (20 mA) point at more
than 0.449 kg/kg, (0.201 3 1.3 + 0.187 kg/kg). (Numbers after the decimal point are rounded up.)
