Setup > Set Zero
The Set Zero process sets a new baseline, or zero, for the
sensors:
CO2
O2
Set zero should take place typically once weekly to maintain
maximum performance, with more frequent use, increase
frequency. To set zero, first press the right arrow to select the
sensor. Wait for a beep to verify the set zero process was
completed. The oxygen sensor uses ambient air as a verification,
which is ~20.9% O2, the CO2 sensor also uses ambient air,
which is approximately 0.04% CO2.
Next, verify the set zero calibration by measuring ambient air.
Run the set zero calibration again if the verification is not
successful.
Setup > Date and Time
