Pact & Fluorescent Lights.
I have 2 pact scales & the dispenser, the only thing that I have noticed is that the scales some times will turn on. When using the comb for dumping powder I have 'Never" had any problems with that operation. I leave both the scales plugged in all the time & turned off, that keeps hem warmed up & ready to go all the time. If you have a power dip , as in gose off for a second, then they will be on when you next return. I had theold model set & had it [Up-Graded] last yr. WOW what an improvement, faster and more accurate. Cost was $50 plus shipping one way. Actually I think they just sent the newer model. My 2¢ Russ.
