Yes, I got into trouble using the Park Tool spec. with this tool. It left the spokes WAY loose!
The one in the link not calibrated anywhere near the Park Tool spec.
Mine came with a printed spread sheet. You have to cross reference spoke material, diameter and use that to determine the reading you need for the correct tension. Spoke tension is measured in "KG Force". There's a range you can use, but the research I did, to answer the question "what's everybody using?" showed 110 KG was a good target. The higher end of the range can be hard on rims, and we already know what happens on the lower end....
