As stated, my new varitas S63 scales won't even hold a zero, it's warmed up for 45 minutes, havnt "burned in" for 24 hours. Every time in place an object it varries .~.2 grns! It says it's stable, level, no Florissant lighting near by, no telophones or draft. I'm just hoping once it's been plugged in for 24 hrs it will settle down. I can't even use it right now, and it cost me $300. HELP PLEASE
