First, I pasted 4 markers on top of one another, and measured their thickness: 0.56 mm
So the thickness of one marker: 0.14 mm. Thickness of two markers: 0.28 mm
I pasted two markers, one opposite the other, onto a 100 mm gauge block.
Next, I scanned these markers and measured the distance between them.
|Gauge block 1||Gauge block 2|
The measured length of gauge block 1 = 100.303 – 0.28 = 100.023 mm
The measured length of gauge block 2 = 100.2116 – 0.28 = 99.9316 mm
Such a big difference can be explained by the different thickness of the markers.
