I bought a plane with and engine analizer UBG-16. I saw thread on selecting an analizer. My question is; does anybody know a source that describes adjusting and setting up the UBG-16 easily. I've tried adjusting the EI UBG-16 by the operating instructions but failed badly; so now I have red warning light all the time. I know I set an incorrect upper or lower limit. Anybody have the simple method? Hugh
