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.

Read post #10. I was noting something relating to his question

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.

Take both domes off and have a look inside. They are domes available that have correction filters built inThey are domes available that have filters built-in. Make sure your domes are filter-free.

As I indicated aready, the both domes in the OP's case are the same, plain plastic domes. And they do not actuate anything.

(And even if they were different, the result of both meters should match. Of course at apt testing.)
