Tracking Force Gauges

I have only coarsely adjusted VTF on my cartridge using a Shure gauge and taking into account the ~ 0.3g overshoot some have reported.

I would like to embark on a careful study of the sensitivity of the sound attributes to small deviations within the recommended mfg's range. I'm curious to know what high VTF sounds like compared to low VTF and to find an optimum setting.

To do this I'm interested in your recommendations on digital VTF gauges with 0.01g accuracy.

I've heard about the MyWeigh scale and others. It seems like the my weigh scale is a traditional looking digital scale in that the measuring platform is very wide with the load cell likley centered beneath the platform. I'm not sure that one gets repeatable and accurate results if the cartridge were to be placed near the edge of the platform if the arm can't be moved in such a way.

Any thoughts on accurate VTF measurements?

I bought one and think it's great. Very easy to use and foolproof.

Sirspeedy,

Have you or anyone you know verified the accuracy of this gauge with a calibrated weight?

Thanks.

Good question. They supply a 5g weight with the gauge, which will re-calibrate to that weight. But I have not verified the accuracy of that weight and it certainly is not of the quality of calibration weights made for the scientific community.

However, for what you say you want to do with it, Andrew, it doesn't matter all that much whether 2.0 grams is actually 1.983 or 2.037. In terms of finding the ideal VTF, you just want to know that it sounds better when the scale reads 2.150 than it does at 2.05. Right?

Drubin,

That's correct. The gauge specifies an accuracy of +/- 0.002g. I would be happy with an order of magnitude worse. All else aside, I feel a lot more comfortable buying a gauge where measurments are perfromed in the middle of the range as opposed to at the bottom end. It also seems that it's easier to position the stylus tip on the center of the measuring platform.

I think I'll give it a try.

Andrew,yes with both the the supplied weight,and with my friend's 800 dollar Winds guage!It's very accurate,and worth the 95 bucks,easily.Believe me,I'm into accurate digital guages,but this new guage is very fine indeed!

Best!
