Calibration for Your Dryer
Depending on many factors, including exhaust run length and termination hood type, every dryer exhaust system is unique. To accurately monitor air pressures for each dryer, the LintAlert is calibrated to recognize the exhaust system’s clean or like new state. As lint builds up over time, the indicator lights illuminate at different rates depending on how efficiently the system is venting at its calibration point.
The lower the initial clean value pressure found, the larger the intervals between a graduation to the next warning level. And, on the flip side, the higher initial clean value pressure found, the smaller the intervals.

Light Meanings During Calibration
(Error Codes)
means no pressure was observed, either due to dryer not ON, tubing not connected or LintAlert was plugged in with tubing connected and dryer running.
means too much pressure was present, likely the exhaust duct was never cleaned or there still exists blockage of some sort.
means calibration was successful and after 2 seconds the first LED will illuminate.
Light Meanings While LintAlert is in Monitoring Mode
Normal exhaust pressure (system clean with a recent calibration).
Exhaust system is approximately 32 percent blocked.
Exhaust system is approximately 45 percent blocked.
Exhaust system is approximately 60 percent blocked. Maintenance is needed.
This critical state is accompanied by an audible alarm which can be muted.
