I've done a search and read lots of posts on this (especially from seemingly anti-G-Shock Sunto owners! ) but can anyone explain the whole thing as I'm still confused.
My local altitude is 100m and yesterday (wearing the watch on my wrist) the watch matched this to within 5m. Taking a walk down hill to town and back it reflected the change and once home again came back to 105m - all good. But last night I noticed the alti was reading at 90 or so and varied later - the watch was off my wrist most of this time. This morning it read 50m and now on my wrist 1/2 hour later it is showing 30m!? Took it off for 15 mins and another reading gives 45m. Obviously during the day, night and this morning the temperature changed from say (on wrsit) 27 deg C to this morning (on table) 21 deg C.
Pressure last night was around 1005mb but this is reading 1010mb this morning.
On the barometer graph the reading at 8am is 3 dots above the one at 6am but I don't think the pressure has hardly moved in that time!
The barometer graph is up and down with dots here and there sometime - not the nice gentle 'line' that I have seen.
Is all this normal?? Can anyone explain how it's algorithms work with regard to temp/pressure/alt and how much of a deg/mb change should affect another reading.
Never had an ERR reading for the A/B functions.
Anyone had a faulty Riseman or compared one sitting next to another?
