2.2 Calibration
A new calibration is required when:
•
The measured O2 percentage in 100% O2 is below 97.0%.
•
The measured O2 percentage in 100% O2 is above 103.0%.
•
The CAL reminder icon is blinking at the bottom of the LCD.
•
You are unsure about the displayed O2 percentage, see Factors Influencing
Accurate Readings in section 3.0.
The MaxVenturi can be calibrated at 100% oxygen or room oxygen (20.9%). The One Touch
calibration will assume one of these two concentrations.
2.2.1 Room Air Calibration
CAUTION: Turn off all flow of gas to the MaxVenturi before calibration in room air.
Calibrating the oxygen sensor in a gas concentration other than room air (20.9%) will result
in an incorrect measurement of oxygen concentration.
