Getting accurate stylus force gauge readings
Posted by Peter C on March 15, 2017 at 05:23:06:
I have an AcousTech digital stylus force gauge. When trying to measure VTF with a Benz Ruby 3, a cartridge with a strong magnetic field, hovering the cartridge above the gauge causes erroneous negative readings. Per an Absolute Sound setup article, you should tare the gauge if that happens. When I try that, the gauge struggles to zero out but eventually loses to the overwhelming magnetic field. Plus, I get a reading when setting the cartridge down which is too high by about .6 gm. If I simply tare the gauge with the cartridge well away, the reading is about .2gm +- the reading I get with the Shure Stylus gauge, so I *think* the reading on the digital gauge is within reason, but I'm not sure ow accurate it is. How do I get an accurate reading with this cartridge? Is there a digital gauge that is immune to these magnetic fields?
