Another thing folks need to remember is that the spokes you use will cause fluctuations in the tensionmeter readings.

For example:

Use a 14g DT Swiss stainless steel spoke on a calibration rig to calibrate the tensionmeter for 100 KGF.

Then . . .

1. Read a CN Mac Series 14g spoke.
2. Read a Wheelsmith 14g spoke.
3. Read a Pillar 14g spoke.
4. Read a Sapim 14g spoke.
5. Read a Wheelmaster / Tsing-Ta 14g spoke.
6. n++;

...your readings will be all over the place.

The are multiple grades of stainless steel on the market. Each has their own properties AND weight for the same 14g.

That will results in variation.

And the manufacturers of spokes all do their differing treatments of the spokes the produce. Each will have their own properties as well.

For my rig I have the following:

1 x DT Swiss 14g spoke. ( High Grade Stainless Steel )
1 x CN Mac Series 14g spoke. ( Mid-Grade Stainless Steel )
1 x DT Swiss 15g spoke. ( High Grade Stainless Steel )
1 x CN Mac Series 15g spoke. ( Mid-Grade Stainless Steel )
1 x Union / Marwi 14g Titanium spoke.

I calibrate with DT Swiss for DT Swiss and Sapim spokes when I know I will be working a number of wheels sequentially.

I calibrate with CN Mac Series for CN Mac Series and Wheelsmith

I calibrate with Union / Marwi 14g Titanium spoke for all my Titanium builds - that's all I get from the customers - Union / Marwi.
