My scale Vs the scrap yard scale??

Balance might be the key with a platform scale. It's just guesswork, but i think the load cell would be placed dead center of the platform.

Try to imagine a 4 foot by 8 foot platform. Place an empty bucket dead center ... and you might get a good reading. Place it the very end of the long end of the scale ... and it might not weigh up at all.



It would be a similar thing when loading the platform. It needs to be loaded either dead center -or- have the weight distributed evenly across the whole surface.

Anyway ... i've noticed that my shop scale reads different from the ones at the yards. I'm weighing up my 12" x 12" boxes on a 12" x 12" postal scale. Everything is centered and balanced. They usually read a few pounds heavier at the yard. It might be because the scale guys don't think to center the load on their scale ? IDK ... it could be that my scale is off too. Been thinking about ordering up a warehouse scale.
