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…
