[QUOTE="stevesmith, post: 1021155, member: 85997"] if its a name you want- ohaus , denver instruments , fairbanks , cardinal , weigh tronix , toledo , lynx etc. but most digital scale being mad these days are quality enough to do the job and do it well as long as it doesnt have a problem..as i had mentioned if it will do the steps i outlined it is perfect and if it want it needs to be returned..having said that most manufacturers are producing a unit with the same wheat stone bridge (load cell) as your name brand scales just being dubbed by whoever puts there box around the electronics..a beam scale has to many friction points to allow for drag or binding to cause them to be very unreliable. they will repeat zero because they were made from zero. but where the fulcrum pivot sits in the bearing cup the pivot is almost sharp as a kinfe blade so it can actually pivot. with just a small amount of wear that sharp edge becomes blunt and rounded not allowing the pivot to pivot it sorts rolls then and can stop off axis actually anywhere with a load aplied except where it truly is..now it can go exactly to the correct weight but when it rolls instead of pivots it cannot by no means at all be correct..dead top center of the pivot in the fulcrum lever is zero so it will go there with ease thats where the false pretense that a beam scale s doin so good because folks think it returns to zero everytime therefore its working properly however thats the fartherest from the truth as it can be.. even your scoop on the end of the beam kangs on a pivot the scoop does not have a cup bearing to sit on the pivot therefore it is riding on a rounded arm of the scoop hanging on the end of the beam so when the beam goed down or up with applied load there is no bearing to sit on the pivot so after using it for some time the scoop will mke a indention in its curved arm that will catch on the pivot at the end of the beam causing huge amounts of friction or drag causing the scale to be impossible to weigh correctly.with load removed it goes back to top dead center where it was made with ease again this is where folks get the opinion there scale is doin good when getting a zero reading is so far from allowing a scale to weigh properly..it took me years of working on these things hands on and many schools to understand what took place while weighing..a beam scale operated exactly as a old truck scale a rail road scale, even the old beams and dials found in your warehouses cotton mills and manufacturing facilities.thats why everybody went digital because they realized they were either loosing tons of money and merchandise or was ribbing the customer of money and merchandise..thats when the department of weights and measures stepped in and started regulating the calibration of all scale being bought or sold across..well were not buying or selling our loads off of them but were sure relying on them being correct to keep our loads consistent..so basically if a electronic scale will pass the build up test which is what i was describing to do to tst if a scale is working properly..if its not doin that then it has a problem because the wheat stone bridge is a resistor in theory so it either works or it doent ..if it works its 100% if it dont its 100% broke i hope this helps to understand the theory behind a beam scale versus a digital scale.. have a blessed day [/QUOTE]
