Has anyone used electronic pocket scales for VTF?

Chris Brady used an electronic jewelry scale with a layover bar to adjust VTF on my arm. The scale had 0.01g incremental gradations and was probably similar to that described above by Elizabeth.

I was very impressed and bought a similar unit, although slightly larger, for $50 with the same sensitivity and tare capability. I couldn't find the model that Chris had gotten for $30.00.

What model was that? I'd be interested in purchasing one.

Thanks for all of the responds. I bought the 120 Z model. I tried the scale at different heights by placing it on and off the platter and still got the same weight reading. The VTF should be the same at about +,- 2 inch from the platter height because the scale didn't detect any difference in 0.1 gram sensitivity. You can try different heights to see if the scale detects different weights. This scale design is insensitive to the the height. The shure VTF gage is sensitive to different heights due to its pivot supported and counterweight balanced. The penny weights is a good way to check the scale.

I got my MyWeigh MX-50 from saveonscales also. FWIW, it resolves to .01g and thus does detect VTF changes at different heights. It reveals VTF changes from arm height adjustments.

Does this matter for listening to music? Not a bit. Except for arm/cartridge changes I use my scale about twice a year, to adjust the counterweight for the hot or cold weather VTF range. After that I use my fine VTF adjuster for tuning by ear, which doesn't require a scale.

Another risk with some of these scales is that some models are strongly magnetic. You don't want a cartridge anywhere near that.

The 120 Z model is non magnetic. The VTF differences at various heights are due to the anti skating device. When the height changes, it either pulls the anti skating string or spring up or down hence changes the VTF. The tonearm pivoting should not effect the VFT at various heights.
