Hi everyone.
I purchased for a very low price a wallner mc 505.
Can anyone help me to understand how its meter function works?
Thank you all, and sorry for my bad english!

Notice the picture I posted of the Wallner modular system 500 in this other thread. I've got the manuals for all of the modules if you think it will help. Get me your email and I'll send what you think might be useful for you.
