I have a similar one. It works, but the problem is getting the right vertical height to place the scale so it is the same height as a record. Typically I have to place the scale on a block off to the side of the platter, and then place the sytlus on the edge of the scale. This seems to work, but it is a lot more hassle than the dedicated digital stylus force scales. (My friend has one, and it works much easier. I did check that the scales measure weights the same, and they do seem to, more or less.)
If you are looking for a small weight to check the scale, a 1982 through current penny weighs about 2.5 grams. An older (pre 1982) penny weighs about 3.1 grams.
