Somewhere in / on the beast there should be a magnetic field adjustment. You play with it (within reason) to get the thing “on frequency”. The real question being: do you care that it’s 1x10^-13 off frequency? In most cases, the answer is no and you move on.
Yes, if you are going to do the adjustment thing, figure out a fixed location before you go to all the trouble. Also let it sit for a bit to “settle in” to the local mag field. I would not play with any adjustments for a week.

I suspect that figuring out a way to mount it to the wall (no rack system here) is going to be my next priority. It can't safely live on my bench or the floor with all those perforations in the case covers.
