Gossen meters

So OP has Lunasix F and Profisix SBC, how is this correctness relevant to his problem? Beacuse it isn't even remotely so.

A friend of mine had a problem with his BMW and I kept telling him why my Fiat was misbehaving, he still couldn't get his head around the problem he was dealing with.

Thanks for the replies.

Kino: These meters are both version of what in the US were called Luna-Pro F and Luna-Pro SBC. These take a standard 9v battery. I’m using a new Duracell battery in each.

Grain elevator: both the domes look the same, no discolouring, but I will clean them both.

Arvee/Ralph: I’ve had the Lunasix F for a while and it gives consistent results, accurate to sunny 16. The Profix SBC was bought recently as a backup. I can’t understand why they match readings in one mode but not the other. Perhaps it is the discolouration of the dome thats creating the discrepancy. As long as I know how each meter responds, I can work with it.
