Calibration sanity check

[heavyg603]

Been using the Touch DRO with my DigiMag scales for a bit now. Once I got the noise issues out of the way everything got easier.  However one nagging thing with the calibration still bugs me.  I started with the 2560 count but on testing with the dials (machine is less than a year old) and the blocks indicated it was off, not a lot but I wasn't happy with a .005 variance over 6".  Then I started adjusting cpis up or down then retesting, arriving at different numbers for all the axis:

X = 2563
Y = 2558.6
Z = 2555.9

Keeping in mind these are all the same scales, iGauging DigiMags just differing lengths.  Just checked them the other night again, they are all dead on.  Does this make sense ?

This is exactly why I added a way to calibrate scales individually. No scale will be dead on the specified CPI due to manufacturing tolerances, etc. My glass scales should be 5080 CPI, in practice they range between 5074 and 5086.

Thanks for the reply Yuriy, glad to hear this is expected.
