Digital caliper: length of step block 120 × 80, width 79.85

Digital caliper: length of step block 120 × 80, width 79.85: a 28-second reenactment recorded in the KELIBRON 3D lab, with English captions. The steps below are the captions in order, and you can do the same measurement yourself in the lab.

What happens in the video

0:00 Digital caliper: length of step block 120 × 80, width 79.85
0:04 Close the jaws fully and press ORIGIN: the display reads 0.00.
0:09 Open the jaws and lower them over step block 120 × 80, width 79.85 until the beam nearly touches the top, square across the two faces.
0:13 Close the moving jaw gently until both faces touch.
0:18 Read while the caliper is still on the part: 120.04 mm, within 119.80–120.20 mm.

Measuring methodsInspecting prismatic parts: block and box checkA prismatic part — block, box or plate — is checked face by face: pick the best-machined face as the reference, measure every outside dimension, step and hole from it with a caliper, then sweep the geometrical tolerances (flatness, parallelism, perpendicularity) with a dial indicator on a surface plate.
