Stylus force digital scales


Digital scales from Clearaudio and others range from $200-500. Amazon has 'em for $20. Why cant I use one of these instead and save big bucks?

After buying and trying many digital scales used for the specific application of measuring tracking force, I agree with Don. This version is clearly superior when compared to similar but smaller scales that use button style batteries. It has the best most solid construction quality, has a non-magnetic platform, measures at the proper height, and provides reasonably consistent readings.
I have one and it works well. It takes watch batteries so pricey to replace. I had the AcousTech- $80, pc board made by the same company- and it operated on two AAA batteries and had an aluminum case. They do stop functioning if you drop them. Both had very repeatable measurements and a calibration weight. The AcousTech held calibration well. Not so much the Amazon version.
one word of caution

If you are using a Clearaudio table with one of the magnetic field arms, you must make sure that the scale measuring point is at the exact same height as the record surface otherwise it could be off considerably.

I use the cheaper model electronic scales ( I have two), and the clearaudio teeter totter scale. When using the cheap electronic ones, I just make sure that I verify their accuracy by measuring the weight of both a penny (2.5 grams) and a nickel (5 grams). Batteries are low when they are off on mine.

Doug, any magnetic attraction with not affect the weight measured. You will see the scale read negative as the cart. nears the scale; but that's because it's being supported by the cueing mechanism. Once the cart. is released all its weight is on the scale and will be measured, magnetic attraction or not. Think about it.

Jim, have you compared how well the clearaudio does next to the digital scales?

I used one of these digital jobs for a while until one of the segments in one of the numbers died. Made figuring out the actual tracking force a real guessing game. Not sure I want to spend so much money again if the same thing were to happen.
