Calibration wrong
#1
Hello All, When I go to calibrate:
1:I have blue scales from Shars
2: I put in to 0.0000
3: X to 30000
4: indicate to 0 with 1-2-3 blocks
5: zero and go to fixed 1-2-3 block
6: put in number that it ends up at
7: when it comes back up it reads 1.800 or 1.799
what am doing wrong or is the Shars scales a different count than Igaging ones? It should read 3.000right?

Thanks in advance Dave A
I use Arduino with photo shield and XLR connectors Huh

Dave,

Unless something changed they are the same scales with different branding and should have around 2560 counts per inch.

1. Make sure you are not in metric mode.
2. Are you moving along the 3" side or 2" side?

Alternatively set the CPI to 2560, "measure" the 123 block and see how far off you are.

Thanks Yuriy, it is at 2555 and its about .0013 to .0008 oversized. is that about what I can get? Or just go up or down on cpi to get best result.
Thanks I really appreciate your help!!!

Dave,
Each "tick" is 0.0004", therefor 0.0008 - 0.0013 over 3" you are roughly one tick off.  Try bumping it up to 2556 and see if you get closer. 
Also, in v2.5 CPI is a decimal value, so you can set it 2555.8, for example.

Regards
Yuriy
