[QUOTE="nheninge, post: 467317, member: 13085"] I am working on validating the numbers my K4000 is spitting at me and need some help, specifically with regards to BARO and ALT settings. I want the unit to give me station pressure, so I set the ref ALT to 0 on the BARO screen, and all is well. (SP = 29.54) On the ALT screen my true altitude is showing correctly for the area (225 feet verified by topo map), but the reference BARO pressure on this screen is 29.82. My actual station pressure is 29.5 and the BARO pressure is likely about 30.05. Adjusting this number only inflates or deflates my altitude falsely. Why is the unit using a number somewhere in between my SP and BARO readings? In the BARO calibration screen I decreased the pressure to reflect my current altitude at the Station pressure. I realize THIS data reflects small changes, but I have a high altitude hunt coming up and I want to understand where these numbers are coming from, and make sure my unit setup is OK. Thanks ahead [/QUOTE]
