High readings at FSM19

Recent plots make no sense at all. Looks like the problem is more complex than I thought. maybe a total rebuild is needed. Started work on the problem. Looks like spikes from the mains, at least I can reproduce some of the issues by switching biggish loads. I'm starting from scratch again, so may be a while before I feed any data. I may put on another counter for a while, but it reads quite a bit higher, it has the advantage of being a bit more stable but no remote sensor.

Whoops magic smoke! Maybe longer offline than planned, in fact it may be a few weeks unless I strike really lucky with some scrounging. Looks like I'm back in business, Power supply fault had fried just about everything.

Spoke too soon. Will now be offline I think for quite a period until bits arrive from China!

Back to square 1.

Fried again?

What happens?

Not sure, but I've been repairing some old equipmen. I'm suspicious that something is arcing and putting out emp. I'm going to switch counters later today and make sure the old gear is off!
