Title: Range switching artefacts?
Post by: mayor on March 03, 2023, 08:03:13 AM
Hello, long time!

On the following graph:

I think the high spikes when the CurrentRanger changes range could be an artefact of the Ranger itself.

Is there something I could look into to address this?

Perhaps modifying the firmware to ignore readings for a bit after a shift.
The raw output will act the same though.

Yeah, I can do that. Do you confirm that such an artefact exists when range switching?

Yes, it's because you're switching the shunts.
