When a certain marking on the vernier scale aligns exactly to the marking on the main scale for a particular object whose dimensions are being measured, the value of the vernier scale reading is added to the main scale reading to obtain the decimal value of the reading in millimeters. hh bb(cm), The test tube hydrometer must not bube hydrometer must no This instrument may be used to measure outer dimensions of objects (using the main jaws), inside dimensions (using the smaller jaws at the top), and depths (using the stem).

Vernier Caliper 1) It decreases the uncertainty of the measurement by calculating the average value. (e. 0 cm), start the stopwatch at the starting point (0 cm) and stop at the To align lines 7 and y, the vernier would have to be moved to the left by 1/25 of a main-scale division; to align lines 6 and 40, the movement would be 2/25, and so on. In each picture, the main scale is on the body of the caliper while the lower scale is the Vernier scale, measuring to 0.005 cm.
