How are these static data curves?

Hi there,

New AQ owner here, got one of the 2nd beta batch. Everything seems good so far. Hoping someone could take a look at my first static run and see if these graphs are good. This is with one corner pointing down. I know I got a little spike in the accels, but hopefully that's OK. My temps seem a little strange, with the one starting near zero and the other two around -20. But the curves are even/consistent. Is this OK?

Thanks!

EDIT: added voltage graphs. Is it documented somewhere which voltages in the log/graph view correspond to which components?

EDIT 2: updated accel voltage graph with correct values

2nd run, opposite corner down. Notice the small accel. spikes in the exact same spots as the first run. I don't think this is caused by anything in the environment (nothing I can think of would happen at the exact same 2 times after I set up the logging). Temp graphs act the same as the first run.

Thanks,

EDIT: updated accel volts graph

Max -

Your curves look really nice to my noob eyes. Good temp range.
Bill's post might answer your questions regarding the noise in the same region and voltage->sensor definitions.

Thanks GF, great link! Turns out I was graphing the wrong voltages for accel. I updated my graphs. The accel voltages have the same little spikes in the same spots as the accel graphs. Curious, but sounds like it's OK.

Off to do my 3rd thaw!

Adding 3rd run, flat this time, top (sensor) side up. Accel. voltages are quite a bit different this time, and the red accel (Z?) line is "fuzzier."

BTW I didn't freeze my SD card with the AQ. I inserted it while the unit was still in the freezer, sealed the box, then removed it from freezer for logging. Figured why take the chance with a fragile memory card, plus I could back up and examine the log files between runs.

Thanks,
