My Brauniger IQ basis altimeter has just stopped working on the A1 meter and is reading '0u' instead of the altitude. It just stopped functioning yesterday when I was up for a quick 45min flight. Has anyone else experienced this? Is it curable or broken? The instrument is now 10 years old so perhaps I need a new one! Any comments or advice on what to try/buy next?
