Happy to help.
Yes reading the instructions manual is a good idea. I spent almost two hours reading the one that came with my scales after it turned off on me halfway through a brew!... So I know it must have been very frustrating for you.
I don't know, actually. I just keep seeing your comments in the DIY forum. You and Chris Bartlett are both in lots of threads there with so much useful info. I don't post often there since I'm just starting to dabble, but I read there a lot.
