MODEL 01015 -Humidity & Dewpoint now registering too high-

Re: Model 01015 - changed batteries the other day and while I had the sensor off, I opened bottom of unit to clear spider webs and dead insects.  Also sprayed some silicone on bottom bearing of anemometer since the cups would not come off as online instructions  direct. Now, both humidity and dewpoint readings are way too high - ten points above what weather service reports. Way out of line for this location. Something happened during inspection and cleaning. How can this be adjusted back to normal readings? (After writing this I saw instructions to bring outside sensor indoors, remove batteries, etc.  Should I try this reset technique?)

If you over lubricated, maybe some of the spray ran down and affected the sensor. It is extremely sensitive to moisture. I know when there is dew on the grass, it reads 99% very easily.

Update:  the unit may be "settling down".  Just now, I compared the humidity and dewpoint readings to official NOAA reports in my Washington DC region and it looks like my sensor is pretty close to being in range, knowing that my backyard microclimate isn't going to match even the closest NOAA station.  Perhaps, as suggested, the silicone spray I applied is evaporating and normal readings are close at hand.  Thanks for the prompt  replies.

Directly related is that I could not pull the wind cups off the 01915 sensor, as hard as I tried. That's why I located and sprayed the bearings at the bottom of the shaft.

Hi Joel,

Are the readings updating correctly now?  The wind cups you are trying to get off, are these on a 5n1 sensor, or a 3n1 sensor?  Thank you. Have a good day.

Hi Jennifer -thnx for weighing in.  I think I spoke too soon about the problem self-resolving.  Just compared my humidity/dewpt readings to the NOAA station they usually most closely match (Reagan and Dulles airports) and they are high again by 5 or 6 pts.  If there is a reset procedure, pls pass it along. 

Meanwhile, I don't know if I have a 5n or 3n sensor (it isn't listed in the manual) but if 5n1 means five-in-one, I think that's it. It tracks rain/temp/humidity/dept/baro/wind(sort of) and the stock market.  Your advice and guidance on the wind cups would be appreciated.  Happy Saturday

The 5n1 has a rain gauge and has a wind direction vane.   It also has one or more solar panels.

The 3n1 has none of those.

Then it is a 5n1. Thank you (hope the manual has been updated).  I think it was good of the support staff to check in on the weekend!

Hello Joel,

Sorry about the confusion between the Five in one, and the Three in one.  To remove the wind cups I have put the instructions below:

Spray lubricant (optional)First, remove batteries from the 5-in-1 sensor before handling to prevent erroneous rainfall or wind readings during handling.

Step 1:
To remove old or broken wind cups from the sensor, secure fingers between the wind cups. Then, pull base of wind cup assembly away from the sensor while securing the sensor with your free hand. Tip: Hold the sensor close to your body to maximize pulling strength. Caution: Broken edges of wind cup may be sharp.

Step 2:
Line up the mounting hole on the replacement wind cups with the spindle on the sensor. 
Tip: Place one drop of light machine oil or spray lubricant on the spindle to ensure the anemometer will spin freely.

Step 3:
Attach the wind cups by inserting the spindle onto the sensor. Apply pressure to ensure the wind cups are properly secured on the sensor.

As far as your readings not being correct, we would recommend resetting both the display and sensor. This is what we call a hard reset. You will lose all readings on your display. I have put the instructions below.  I would recommend resetting the weather station when your local barometric pressure is at 29.92. 

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 1 minute to ensure any remaining battery power is discharged from both units. 
  5. Make sure the A-B-C ID code switch on both units match. 
    *Sometimes changing to a different ID code can help.
  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 20 minutes to ensure a wireless signal is received. 
    * 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
If you continue to have this problem, please contact our AcuRite customer support at 877-221-1252. Thank you. Have a great weekend!

Will do what you suggest. Did try (hard) to pull off wind cups but stopped for fear of breaking them. Will try again

Hello Joel,

If you are replacing the wind cups on the sensor, it is ok if they break you just don't want to twist or turn. The shaft the cups go on is the part that you don't want to bend or twist too much. Some people have even used a needle nose pliers to get them off. Thank you. Have a good day!

Got it, thanks.  They are on really, really tight and I don't aim to break them so I may just have to accept the abnormally low settings and multiple by about 3.  The shaft seems to turn freely anyway and lubing may not bring them up anywhere near true wind speed.  Shame the recommendation is to mount at 33' - I get  altitude sickness around 27'

Hello Joel,

Mounting at 27ft will have a very accurate reading.  Weather stations have their wind sensors mounted at 33ft.  Our recommendation is at least 5ft.  The higher the better of course.  Please let us know if you have any other questions.  Thank you and have a great day!
