Check the
measured
values shown in
Vol% in the
EtCO
2
digital
display.
Press the gas
valve for 15
seconds until the
readings stabilize
Calibration is not required if the measured value is the same
as the concentration of the calibration gas (±0.5%) e.g.
Concentration of calibration gas used is 5% (CO
2
); the
measured value should be between 4.8%-5.2%, therefore,
calibration is not required.
To reset and
return to
measuring
mode
(automatically
erasing event
messages) long press
To exit service
mode and save
event messages Turn off the

If the reading is outside these limits, calibration is required.
Refer to Table 10-2: "Calibration Process" for the calibration
