- 7. Disadvantages of Mechanical Comparators •Limited Magnification •Compared to electronic or optical comparators, mechanical comparators have lower magnification and sensitivity. •Friction & Wear •Since they rely on mechanical linkages, repeated use can cause wear and affect accuracy over time. •Hysteresis Effect •There can be a slight lag in the pointer movement due to mechanical resistance, leading to minor errors in measurement. •Delicate & Sensitive to External Factors •External vibrations and temperature variations can affect the accuracy of measurements. •No Direct Reading of Dimensions •Mechanical comparators only show the deviation from a standard, requiring additional calculations for absolute measurements. •Limited Range •Suitable only for small measurements; they cannot measure large deviations effectively. •Operator Dependency •Measurement accuracy depends on the skill of the operator, as improper handling can lead to errors.
