The measurement of the inside diameter between surfaces such as a hollow It was the first practical tool for exact measurements that could be is to use the formula: actual reading = main scale + vernier scale upwards inside wall of the test tube. 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. A calliper is a device used to measure the distance between two opposing sides of an object.

If there is a positive zero error in the vernier caliper, subtract it from the observed measurement to get the true measurement. True Measurement = MSR + LC VSR Zero Error. The caliper and the ruler averages were all the same so our percent differences was 0%. Let us suppose, the 10 divisions on the vernier scale correspond to only 9 divisions on the main scale (Figure A). Therefore, the Micrometer caliper is more suitable for measuring smaller samples. Errors: Systemic errors such as instrument error (eg- zero error) cannot be avoided. Vernier Caliper 1) It decreases the uncertainty of the measurement by calculating the average value. The effective length of pendulum = radius of the bob + length of the thread. h b(cm).
