By unwinding this screw you increase the preload on a worn, softer spring so that a tension meter behaves as a factory one would.

Couple of adjustments were made and then I took final tension readings with the same spoke. Now, final spoke readings were taken and results were I must say satisfying. The tension meter started behaving almost as the factory one would. Check the table below to see results. However, some deviations were still present at low tension values. Performing a tension meter calibration only using one reference spoke can be sometimes misleading.

The thing is that with a different spring preload than it originally was, the spring may behave differently and readings across multiple spoke models or spoke tension values can become inconsistent according to the original tension charts, supplied with the tool. Also, it was my client request to check higher tension values with some smaller diameter round spokes that he also uses frequently. Fortunately I had one Sapim Race spoke, a single butted 1. Tables below show actual readings match with factory calibration of the tool.

However, another small spring preload adjustment had to be done. But all in all it looked that this Park Tool TM-1 could continue doing its job! With some use, a wear and tear is pretty ordinary for every spoke tension meter.
