Thanks to my good friends I had chance to measure my LOLO5 logger in calibrated pressure chamber. We were “flying” more than 60 minutes up to 4000meters ( more than 13.000 ft). Although LOLO5 was designed for RC model users i.e. approx. up to 1000meters (3.300 ft), error in 4000meters was 6,4% (254m/833ft). Bellow you can see altitude log, deviation table and measuring devices configuration.
During measurement and changing flying level I had also chance to check accuracy and sensitivity of LOLO5 vario part. Deviation was about +/- 0,1m/s. All in all I would sum up-very good device.
