Inaccurate Barometric Pressure

Follow

 

The Learning Mode algorithm begins with global average pressure (29.92 inHg). The weather station then takes 4,000 readings at 12-minute increments to calculate a running average and compute the barometric pressure for your exact location.

The pressure accuracy of AcuRite self-calibrating forecasters increases with each new reading over the Learning Mode time period. After 14 days, the Learning Mode icon disappears from the weather station screen. At this point, the self-calibrated pressure is reasonably accurate (although the algorithm continues to run; 4,000 readings = 33.33 days).

 

If the barometric pressure is inaccurate:

  1. Please allow up to 14 days for the pressure to calibrate itself to your location.
  2. If the display has been powered on for 33 days and has not been reset within the learning mode, perform a factory reset the display. Most displays will have a reset button located in the battery compartment. If the display does not include the reset button feature, remove the batteries and/or power adapter for 2 minutes to reset the display.
