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?

Aoliviero, the surface that is used to rest the stylus on is non-magnetic genuine stainless steel. It also has a thin plastic or nylon type pad with a bull's eye glued to the recessed center of the scale's metal pad. This "landing zone" is slightly concave. I guess this is there to help center the stylus and give more consistent readings as well as potect the stylus. If you place the stylus on the bull's eye, your stylus has no where to move but up hill. While this unit is built to a price point, it is also well thought out. It has nine felt feet on the bottom to protect your platter, you can turn the readout light on or off and the scale pad has a built in cover to keep the dust off the LZ to help keep your little diamond clean. It comes with a 5 gram test weight, three batteries, a vinyl case and you can calibrate the readout. Unlike many gadgets in our beloved hobby, this one has real bang for the buck.
For what it may be worth, I have a lab certified 2 gram weight and today this new scale from Singapore read exactly 2.000g nine out of ten times. One time it read 1.998g. Last week, it read 2.000g ten times in a row. It also seems to be very consistent in its readings when used with a cartridge. It may be worth every bit of a C-note.
I said the gauge comes with (there are several jokes here but I better leave it alone) three batteries when in fact it comes with four thin watch type batteries. It uses two batteries at a time so you have a spare set. I guess battery life is still an unknown at this time.
