Hi All, thank you for reading. I have 2 tm-1 and discovered the difference. My older one read 1 unit higher whether for aero spoke or non aero one.
My observation, the new one has 2 spring revolutions and adjustment screw is adjusted longer while the older one has 3 spring revolutions but shorter screw. New one fells harder when trying to press to measure.
Should I try to adjust the adjustment screw?

These gauges aren’t perfect and you’re bound to see differences between two, even if they were tensioned or dialed in exactly the same.
When I first got into wheel building I was annoyed to find that testing the same spoke tension multiple times with the same gauge would give me different values. I think there’s just an inherent error with these devices.
That said, the new one could reasonably be more accurate due to having more recently been calibrated.
