The thin metallic strip of vernier calliper moves downward from top to bottom in such a way that it just touches surface of breaker. Main scale reading of calliper is 8.6 cm, whereas its vernier constant is 0.1 mm. The 4th of V.S.D. is coinciding with any main scale division. The actual depth of breaker in cm is (when zero of vernier coincides with zero of main scale).
