If you do not observe this restriction, the measurement will be invalid, and any previous valid
value will be used. The gray area in figure represents the valid setting range.
Setting example 1
If the range minimum (corresponding to 4 mA output) is set to 10 vol%O
2
then range maximum
(corresponding to 20 mA output) must be at least 13 vol%O
2
.
Setting example 2
If the range minimum (corresponding to 4 mA output) is set to 75 vol%O
2
then range maximum
(corresponding to 20 mA output) must be at least 75x1.3=98 vol%O
2
(rounding decimal part up).

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 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.
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.)
