Help again. Powder scale ?

[grayfox]

I don't know that it necessarily hurts it to leave it on. but I turn off after I'm done, the 30 min warmup, there's always something else to do to occupy that time. Electronics like that I don't like to leave on, it sort of sets it up for any power surge that could come along, thunderstorm, things like that. You're going to want to do a wt test on powerup every time anyway, this way you also get to watch it power up and do its own self-test...
