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…

Wireless signal is intermittent or not working

Simply moving your display console (or receiver) to a different location may easily fix the communication issue. We recommend the following best practices for trouble free wireless communication. Fresh Batteries. If applicable, make sure there are fresh batteries in both the console and remote. Remember…

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…

Weather Station Temperature Reads Too High in the Day Time.

Temperature reads too high (or inaccurate) when placed in the sun or close to a radiant heat source, like a house, building or structure. Place the sensor inside next to the indoor console sensor. Wait about 1 hour for stabilization. The sensors should agree within…

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…

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….

How do I Calibrate Barometer (Relative Pressure), WS-2800 Series.

You will want to calculate your barometric pressure to an official reporting station in your area.  Since barometric pressure does not drastically change in a 50 mile radius (unless the weather is rapidly changing), this method of calibration is acceptable. To determine the relative pressure…

Weather Station Console is Showing the Wrong Day of the Week.

If the weather station is showing the wrong day of the week: Make sure the year is correct. Make sure the month-day format is MM-DD and DD-MM (day/month vs month/day). Make sure the time zone is set correctly if the console time is radio controlled…

How do I turn on or off the scroll feature on the WS-2801?

If you have multiple wireless sensors, while in normal mode, press the SET/CH key to the different channels. Temperature, humidity, and MAX/MIN records will be displayed for each channel. To scroll automatically, press the channel button again, and the scroll icon   will be displayed next…

Backlight is low or off, WS-2800 Series

The backlight has three settings – high, medium and low. Press the LIGHT/SNOOZE button to toggle the screen brightness between HIGH, MEDIUM and LOW. If the backlight does not stay on, Check the AC adapter is working. Remove the batteries but leave the console plugged…

Temperature Reads too low at night.

Temperature can read too low (or inaccurate) at night when placed close to a radiant heat source, like a house, building or structure.  It can also read lower then other stations in your area due to irrigation or sprinklers. Place the sensor inside next to…

How do I Perform a Factory Reset, WS-2800 Series.

To perform a factory reset of the console, press and hold the SET button while the console is powering up. After the power up sequence is completed, let go of the SET button: Remove the batteries Disconnect from AC Power. Press and hold the SET…

How do I Calibrate Temperature, WS-2800 Series.

Temperature errors can occur when a sensor is placed too close to a heat source (such as a building structure, the ground or trees). To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Here is an example: https://www.amazon.com/dp/B00551N8Q2 Bi-metal (dial) and digital…

Console Flashes or Resets, WS-2801 Series.

If the console flashes or resets randomly and repeatedly: Check the connector in the back of the console for a lose connection. Check the AC adapter for a lose connection. Remove the batteries and plug back in. If the problem persists: We have a one…
