Zenister 0 #1 February 9, 2003 my room mate had my gear shipped up to me in Seattle i check my altimeter says 10k. idid it really 10 k and to zero it i turn it down (9,8,7)? or did it only lose 2k from its last zero at eloy? and so is -2 ?? i know it went by air to get to me so i'm thinking there isnt really any way to tell when the change occurred which direction it was is there? so how do i know which way to zero it? feels like this is a stupid question for some reason.and funny that altimeter isnt in the dictionary..____________________________________ Those who fail to learn from the past are simply Doomed.

PhreeZone 20 #3 February 9, 2003 Whats your field elevation and whats Eloys Unless you are above 3000 feet MSL anything the alti reads will show you being negative. IE 0 at Eloy (lets say 4000 feet), ship it to you at 2000 feet will be -2000 feet or 10k on the alti Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites
pilotdave 0 #4 February 9, 2003 The position of the dial has no affect on the internal workings of the altimeter. You don't need to "unwind" it. Just spin it whichever way is more convenient. Dave Quote Share this post Link to post Share on other sites
sdctlc 0 #5 February 9, 2003 The altimeter went down in elevation. Eloy is approx 1500-1550' MSL and Seattle is basically SeaLevel. If you are at one of the DZ's around seattle it would be higher or closer to zero on the dial since none of the DZ's here are actually at SeaLevel. The altimeter was probably affected by the lower "end" location compared to its start shipping point. It also could be additionally affected by a barametric pressure difference. Basically turn it the shortest didtance to the "0" Scott C."He who Hesitates Shall Inherit the Earth!" Quote Share this post Link to post Share on other sites
LouDiamond 1 #6 February 9, 2003 hey Zen, just hit the reset button on the bottom and let all the barometric pressure escape out of the unit. Be carefull though, it comes out of the unit like compressed air but harder "It's just skydiving..additional drama is not required" Some people dream about flying, I live my dream SKYMONKEY PUBLISHING Quote Share this post Link to post Share on other sites

skr 1 #8 February 9, 2003 >or did it only lose 2k from its last zero at eloy? and so is -2 ?? I think it's that. The needle went counterclockwise from 12,000 to 11,000 to 10,000, so you should fix it by moving the needle clockwise from 10 to 11 to 12. It matters which way you turn it. I took one apart once. The needle was attached, through several gears, to a little metal bellows which expanded and contracted as outside pressure changed. If you turn the needle the wrong way to zero, then the inner workings are really at + or - 12,000 ft, and it wasn't meant to be used that way.
