CO
2
gas density calibration and Auto Zero adjustment
MCO-18AIC provides both the manual CO
2
gas density calibration and the automatic Auto
Zero adjustment.
1. CO
2
gas density calibration
When either the CO
2
density SV or the display value is not match with the actual value,
calibrate CO
2
gas density according with “CO
2
calibration” (Page 9) to input the actual
value again.
2. Auto Zero adjustment
Refer to “Auto Zero adjustment”
3. The relation the CO
2
gas density calibration with the Auto Zero adjustment
The description is as follow.

Ideal line for the set value and the actual

(Note) In fact, it could not make a straight
line due to the characteristics of the
sensor.
