Yes, I have the calibration rod also. But there must be some type of table that tells you what the readings mean. For example-lets say you want to adjust a 5/32 shroud to 10% of it breaking strength. I can find out what that number is from the wire manufacturer, but how does that number relate to the tension meter? Do you have instructions with it?
Also, the tip that has the ridge that contacts the shroud looks a little worn on mine and it looks replacable. Any idea if these are still available? It looks like a very expensive meter. I would hate to have to go out and buy a Loos meter.
