About Input Ranges

The minimum concentration of oxygen for the minimum current (4 mA) is 0% O

2

or 6%

to 76% O

2

. The maximum concentration of oxygen for the maximum current (20 mA)

ranges from 5% to 100% O

2

, and must be at least 1.3 times the concentration of oxygen

set for the minimum.

Setting example 1

If the setting (for a 4 mA current) is 10% O

2

, you must set the oxygen concentration

for the maximum (20 mA) point at more than 13% O

2

.

Setting example 2

If the setting (for a 4 mA current) is 75% O

2

, you must set the oxygen concentration

for the maximum (20 mA) point at more than 98% O

2

or greater, (75

ϫ1.3% O

2

).
