Trusty old AR stylus gauge.. checked it's accuracy on a very high dollar calibrated digital scale that measures to .01 grams, and my simple little AR beam scale is very accurate. I calibrated the 1 gram weight as it was a little less than 1/10 gram too heavy. And no batteries required! I wonder how many of these are still in use these days and have all the pieces together :scratch2:
ed, I have absolutely no disbelief in what you have said, that inexpensive, old trusty scales such as this, and others like the Shure are very good, and accurate.
Good enough in fact, that one should not hesistate setting up a $7500 Cartridge with them, once they know just how accurate they are by some simple tests-checks.
With any Beam-Type Scale, it is a bit hard, setting a reference lab weight upon them to confirm accuracy. This is of course easier to do with a digital scale.
I had my own doubts with the Proscale LC-50 I bought from Old Will Knot for $29, until I seen lab reference weights thrown on it, and a 1.00g weight read 1.00g, a 2.00g read 2.00g, a 5.00g weight read 5.00g, and so on, and so forth up to 50.00g, with dead on accuracy.
With a better scale, a teeter-totter type can be checked, via the Arm-Cartridge itself. A more important feature-quality of a scale, is repeatability, rather than utmost exacting accuracy. It supposed to be the ear, which can identify the best tracking force, rather than trusting any scale, including the $800 Winds Scale. Mark
