The CO
2
calibration value setting is completed or canceled, and the CO
2
CAL screen
opens.
* The display on the left shows the calibration value set
to 60.0% CO

.
11.
Set the needle so the CO
2
standard gas can be suctioned.
12.
Hold down
for 1 second or longer.
The CO
2
calibration starts, and the Stability Decision screen opens. The CO
2
calibration value on the lower line
flashes.
A beep sounds, CAL complete appears (approx. 1 second), and then the O
2
/CO
2
MEASURE screen opens. The
calibration process is completed.
• The calibration value is saved even if the power is turned OFF, the batteries are removed, or the AC adapter is
disconnected.
• If the settings have been initialized (refer to page 18 ), the CO
2
calibration value will be initialized to the factory
default state. However, the display on the setting screen will continue to be the most recent CO
2
calibration setting
value.
• If an error message appears, refer to the section “Error Messages” (page 32 pages) and confirm and remedy the
situation.
Set and perform the CO
2
calibration with standard gas in the concentration range between
15 and 90%CO
2
. If calibration is performed with a value exceeding this range, the CO
2
measurement value error may increase.
... The CO
2
calibration value increases by 0.1% CO
