To check the contact force, the tonearm balance (in our case a tilting rocker, but there are also digital models) is first positioned on the platter. It is important that there is no mat on the platter, otherwise, the measurement will not be accurate, as the base dampens the tilting moment. Therefore, please always use the smooth turntable.
The needle with the tonearm is then lowered onto the scale. The tip should lie at the point corresponding to the support weight. It should be noted that each system behaves differently and each has a different support force, which can be found in the description. It is the same, however, that the information is always given in grams. In concrete terms, this means that you have to convert: The support force on the tonearm scale is given in millinewtons (mN), which corresponds to about one-hundredth of a milligram (mg). 10 mN is about 1000 mg, which corresponds to about 1 gram (g). If, for example, the pick-up shows a contact force of 1.5 grams, the needle tip is set to 15 mN.
Now you have to see if the rocker tilts forwards or backward and change the tonearm weight accordingly until it is in the balance. As soon as this happens, the correct support force of the tonearm is reached.
We hope that with this manual we have been able to help you adjust the support force of your turntable and will be happy to answer any further questions you may have.
