How to Read
STEP 1 · MAIN SCALE
Read mm before the zero of vernier scale:
— mm
STEP 2 · VERNIER
Find vernier division aligning with main scale:
Division — × 0.02
STEP 3 · TOTAL
Add both values:
— + — = — mm
Measurement Tips
Cylinder: Close lower jaws around the widest part. Keep caliper perpendicular to axis.
Ball: Ensure jaws touch at maximum diameter. Rock slightly to confirm.
Zero Error: Always check zero before measuring. Close jaws fully — reading must be 0.00.
Least Count: 1 ÷ 50 = 0.02 mm precision guaranteed by the vernier principle.
