Webb22 nov. 2016 · Procedure Find the value of one linear scale division (L.S.D.). Determine the pitch and the least count of the screw gauge and record it step wise. Bring the plane face B in contact with plane face A and find the zero error. Do it three times and record them. If there is no zero error, then record zero error nil. WebbProcedure: Place the lower jaws closed and check if the zeros of both scales coincide. Now, loosen the screw of the vernier scale and move it towards the right side. Place the given object (blackboard chalk) and tighten the vernier scale. Hold the instrument exactly below your eyes to avoid parallax error, which may result in false results.

In order to measure an object, the object is placed between the jaws and the thimble is rotated using the ratchet until the object is secured. Note that the ratchet knob must be used to secure the object firmly between the jaws, otherwise the instrument could be damaged or give an inconsistent reading.
