Question

After using your balance how should it always be left?

Answer 1

I don't know the kind of balance you are using. General rules are

Leave the door(s) closed.
Nothing on the pan(s).
Leave the knife edge arrested (if it has a knife edge)
I suggest you google this and look for the kind of balance you have and read that. That way you will get up to date information and it will be specific to your kind of balance.
