8. Detailed Data Setting
“Mixing ratio” setting range
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
ϫ 1.3 + 0.187 kg/kg). (Numbers after
the decimal point are rounded up.)
