G'day,
I am having some trouble with the altitude measuring function on my HRM. I have tried recalibrating (entering altitude when I have a ref point), and sometimes it seems fairly accurate, but 80-90% of the time the altitude readings are way off. For example, I did a hilly ride which I know has maximum altitude around 200m and minimum around 10m, and it seemed accurate for the first 20km, but after that the altitude just sat at over 7000m without much change. Reviewing all my training files, it seems to like being at 1506m, 5346m, 7694m and nothing in between. My climbing's not bad, but I think I would notice that much altitude gain!
I know the altitude function can be a little inaccurate, but this seems ridiculous. Any suggestions would be greatly appreciated.
Thanks.
