Recalibration
CO
2
Zero Reset:
The Elem
e
nt CO2 is equipped with a self-calibrating sensor that can be reset by the user at
any time using the CO
2
Zero Reset feature. The reset feature adjusts the calibration of the CO
2
channel by taking the current reading of the sensor and “zeroing” it to 400 ppm (outside air
concentration). To do this expose the data logger to outside fresh air for at least five minutes to
stabilize. Then press and hold the scroll and wireless keys for three seconds at the same time.
The message “zeroing CO
2
” will appear on the device screen. The message will disappear within
30 seconds and the device will beep twice confirming the zero operation is complete.
Depending upon device exposure to extreme parameters and frequency of use, MadgeTech
suggests performing the CO
2
zero reset as frequent as needed for application accuracy.
CO
2
channel calibrated accuracy: ± 70ppm + 5% of range, add 8ppm per day of continuous
monitoring from zero reset.
