Hmmm this was the result of the last freeze attempt with the board in the same orientation as it was for the first run and the results look almost exactly the same. Not much else I can do other than pack the board with more foam?

Many thanks, David

Glitch appears at the same time / temperature with the board mounted level too :?

This is the 4th time a glitch has appeared around 170.000 which equates to 22 to 24°C ... maybe it's an inherent bug in the sensors? I think I'll start a new thread for this issue, as it's not really related to my original problem of getting empty log files ...

Any thoughts are still most welcome :)

David

To me it looks like a sensor characteristic. Cal will eliminate this.

Hi Christof, yes that's what I thought too. I'm doing one more logging test now, but I imagine it will produce much the same values. It's interesting that the glitch doesn't always affect the blue line, and never seems to affect the red line ...

Cheers! David :)

David,

I have calibrated boards that show these glitches without incident.
