Question
How can I calibrate the internal barometer on my Orbisphere controller?
Summary
Steps to obtain the correct calibration of an internal barometer on an Orbisphere controller.
Answer
To calibrate the internal barometer of any Orbisphere instrument you must first obtain the local barometric pressure. 

If you have a barometer or an absolute pressure gauge at your location it is simply a matter of entering the value, in either bar or mbar, in the Orbisphere controller under the barometer calibration menu.  This procedure will vary by instrument type.  See associated controller manual.

If your local airport has a website which gives weather data you may be able to use as their values will be local and adjusted for elevation.

If you do not have a barometer or an absolute pressure gauge at your location and want to get the barometric pressure from the internet such as the Weather Channel or any other national application, you will need to calculate the value for your local area. Barometric pressure given is adjusted for sea level on these types of applications. You will need to take the barometric pressure reading and factor in the elevation at your site.  Remember as elevation goes up, pressure goes down. There are sites on the web for adjusting barometric pressure based on elevation such as the one on the link below.

To find your local elevation if it is not already known you can use the link below.

Once there you can search under the appropriate names to find one close to your location.
