If this is off topic please obliterate it (and if anyone is interested I would love to hear from them via PM).
I have a problem with understanding the barometer on a PRG80. I have had the watch a week and I have previously owned a casio altimeter/barometer so vaguely understand how they are meant to work.
I hadn't previously concentrated on the barometer but as far as I remember it has been showing a complete graph showing perfectly credible trends. Today it has gone mad.
1100 put on watch, raising temperature from 20 c to 34 c (house heat to blood heat)
1120 set reference altitude
1120- 1330 climb 300 m to 580 m and back down again. Altimeter agrees exactly with car gps and with spot heights on map at 460m and 580m. climb is accurately stored in periodic records. Therefore presumably not a pressure sensor issue.
Barometer graph like this:
12-2 one blip only visible, bottom row right column of graph
2-4 complete row of blips alternating between top and top but one row of graph
4-6 one blip only visible, top right of graph this time
6-8 two blips visible, the top right one above now moved 1 column left and a new one in right hand column two clear rows below the top row.
8-10 nine blips all on the bottom row with various gaps. Most recently: there is a new blip at bottom right then gaps for the previous two columns (the 4 pm and 6 pm readings) The pressure reading was 1020 at 6 pm, 1006 at 8 pm. I haven't noted any previous pressure readings but they have not been fluctuating wildly.I think the problem is specifically with the graph. I haven't checked readings withanother barometer
Obviously the watch has gone mad. I have looked at the instructions for calibrating the thermometer and barometer. The factory setting is " off" in both cases. The barometer was set at "off" where I left it. The temperature was showing the current temperature as a reference setting so I changed this to off.
Is any of this explicable and/or is there any way of rebooting the watch, or do i need to return it to Casio?
