What is the difference between absolute and relative pressure?

Absolute pressure is the measured atmospheric pressure. Absolute pressure is not corrected to sea-level conditions. To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions (referred to as relative pressure, or pressure relative to sea-level). Because the air pressure decreases as…

How do I update the Console Firmware, Observer Series ?

To check your current version of firmware, go to the Factory About| Display from your Display Console (press the tool icon on the display four times, or ): The firmware in this example is 2.3.1. The update procedure is as follows: 1. Download the latest…

How do I test the accuracy of my rain gauge?

To determine the accuracy of a digital rain gauge, you need to know the surface area of the funnel. If the rain gauge has a rectangular inlet: Area = length x width If the rain gauge is circular: Area = ( π x d2 ) /…

Rain not reporting or under reporting, Observer Series

If the rain is under reporting, loss of reception may result in uncounted rain with older firmware. You can update to the latest firmware here: https://www.ambientweather.com/amwewswsdo.html For WS-1000, WS-1001, WS-1002, WS-1200, WS-1201 owners: Your display may be showing rain rate (in/hr) and it has not…

Wind Speed or Wind Gust Appears to Read Low.

This is a very common complaint with weather station owners, regardless of model numbers or manufacturers (from the low cost $100 weather station to $1000+ weather stations). Many of the units returned to us meet their accuracy requirements based on a constant speed fan test….

Rain Increment Definitions

Your weather station may only display some of the following increments of rain. Please refer to your User Manual for details. Here are how increments of rain are defined: Rain Rate is defined as the rainfall in the last 10 minutes, multiplied by 6  (10 minutes…

Testing the accuracy of a hygrometer - saturated salt test

The saturated salt solution test is an easy method for testing the accuracy of your humidity sensor. Most electronic sensors are accurate from +/- 3 to 5% humidity, and some weather stations or weather centers can be calibrated from the display console by applying a…

How do I prevent snow build up on my weather station?

Snow build up is difficult to prevent, especially “wet snow”. You can spray the top of the unit with teflon snow and ice repellent like this: https://www.amazon.com/DuPont-Teflon-Snow-Repellant-10-Ounce/dp/B0031T82NO but this is not 100% effective. Snow is considered normal maintenance, and accumulated snow can be brushed off…

How can I test the accuracy of my hygrometer (humidity Calibration)?

Place the sensor inside next to the indoor console sensor. Wait about 24 hours for stabilization. The sensors should agree within the accuracy specifications. Most digital capacitive hygrometer sensors are accurate within +/- 5%. Thus, the sensors should agree within 10% when considering full tolerance…

Temperature does not change, example, -40 or 140 degF, Observer Series

If the temperature does not change, or is stuck at a specific value:  Cover the solar collector with your hand.  Press and hold the reset button on the sensor array (#6) for about 10 seconds: Replace the batteries. We recommend Lithium Energizer Ultimate Batteries. Please…

How long will a weather station last?

A weather station’s life is greatly impacted by the environment. In general, a user can expect a 1 to 10 year life before replacing the sensor array. Salt Air. Salt air and salt spray is the most difficult environment for weather stations. They corrode bearing…

Wind Direction is Wrong.

If the wind direction is incorrect, it is likely a calibration issue. You must calibrate your wind vane to true north using markers on the wind vane. This procedure is described in your product User Manual. Some other common mistakes. Wind direction appears 180 degrees…

Console does not power up, Observer Series

If your screen does not power up, or the console is blank, press any of the keys on the display. If it does not display: The issue may be with the AC adapter. Measure the output voltage of the AC adapter, and it should be…

Relative barometric pressure does not match official source.

Your relative pressure likely does not match the official source because you have not calibrated it properly. You will need to reference your User Manual for correcting relative pressure. Discussion: To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions….

Rainfall spikes, or over reporting.

Rainfall spikes, or over reporting is generally caused by pole vibration. Pole vibration can occur when it is very windy, or a bird lands on the weather station. Hail can also cause the rain gauge mechanism to vibrate. Make certain the pole is not vibrating during…

How do I read indoor conditions on Weather Underground?

Weather Underground only provides indoor data in their iPad application Wunderstation. However, AmbientWeather.net fully supports indoor and multiple channel sensors. Here is a complete list of weather stations that work with AmbientWeather.net: https://www.ambientweather.com/ambientnet.html  

Outdoor temperature is inaccurate or drifting, Observer Series.

Replace the batteries. We recommend the following batteries: https://ambientweather.net/help/my-rechargeable-batteries-no-longer-work-which-batteries-are-recommended-for-my-weather-station/ Clean any corrosion around and on the battery terminals. If the problem persists, the sensor array must be replaced. We have a one year warranty. To replace under warranty, please visit: www.AmbienetWeather.com/rma.html If out of warranty, a…

Weather Station Grounding.

Because lightning is so unpredictable, we cannot make important decisions about your individual installation. If you are installing the weather station on your roof or structure, consult a licensed electrician that specializes in lightning for advice. Because weather stations are not hardened against EMP damage…

How do I Calibrate the Wind Direction?

To calibrate the wind direction, select the Calibration Panel from your display by tapping the Tool Icon four times: Enter the correct current Wind Direction into the Display Console: If you live in the Southern Hemisphere, point the solar panel to the North and calibrate…

Can the Weather Station Measure Snow?

Most weather stations use self-emptying rain gauges, which do not count snow and will not operate when frozen. It requires the snow melt before the precipitation is “counted”.
