MY SYSTEM IS 1 WEEK OLD! fROM WHAT i'M READING FROM OTHER CUSTOMERS THIS IS A PROBLEM FOR MANY. I think I made a mistake buying this product. Purchased it on Amazon. I could have used the money for BUYING something OF quality. NOT IMPRESSED AT ALL!!!

Since your unit is only 1-week old, it hasn't completed the 2-week learning period for adjusting the pressure to a sea-level equivalent.

The calibration on PC Connect adjusts the information sent to myAcurite and wunderground.  It does not change what is on the display.

As for the humidity, have you checked to make sure you haven't installed too close to a humidity source?  (lawn sprinklers, pool, etc.)

Hello Frank,


We have replied to your other post on the community forum with the following information below.



 What is the model number of your outdoor sensor?  Please try the troubleshooting steps below:

You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios. Follow the battery guidelines below:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.

•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.

•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.

•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.

•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.

•Mixing different battery types (brands, old/new, etc.) is not recommended.

Perform a hard reset:


1.Bring both the sensor and display unit indoors side by side.

2.Remove batteries from the sensor.

3.Remove batteries from the display unit and unplug the AC adapter (if applicable).

4.Wait 2 minutes to ensure any remaining battery power is discharged from both units.

5.Change the A-B-C Channel on both the display and sensor making sure they both match.

6.Reinstall batteries in outdoor sensor first.

7.Reinstall batteries in display unit second.

8.Let the units sit within a couple feet of each other for 30 minutes when comparing for accuracy
* The display should receive the signal within several minutes.

9.After a connection has been established you may place the sensor outdoors.
*If the signal connection fails after the units are separated try a new or different location for the display unit, the sensor or both
