Question

State the precautions for handling vernier calipers for measuring the dimensions of any object. ​

Answer 1

$\huge\underline\blue{\sf Answer}$

✴Vernier calipers is used to calculate the accurate measurement between two markings by using mechanical interpolation.

✴mostly used to calculate the diameter of objects.

PRECAUTIONS FOR CARRYING VERNIER CALLIPIERS FOR MEASURING THE DIMENSIONS :

✴ we should not slide the vernier calipers over main scale vigorously or fastly. it should be moved smoothly over the main scale.

✴The object whose diameter should be measured is holded gently between the ends. the object may be spherical ball,, cylinder etc.

✴The zero error for the measurement of depth is different from usual zero error so it should determined separately.

✴The zero error if any should be noted carefully with a proper sign are only taken into consideration.

Answer 2

The precautions for handling vernier calipers for measuring the dimensions of any object are as follows-

• When using the vernier caliper, clean off the tool properly to remove any dirt, rust, or grease to avoid any error during measurement.
• The object being measured should be held gently, without much force on the jaws of the caliper so it won't break while handling.
• The scales of the caliper should be moved slowly and smoothly and the locking keys shouldn't be too tight for accurate measurement.
