Question

The ratio of the change of instrument indication to the change of quantity being measure is termed as ______
1. range
2. consistency
3. sensitivity
4. accuracy

Answer 1

Correct Answer - Option 3 : sensitivity

Explanation:

Sensitivity:

• It is defined as the ratio of the changes in the output of an instrument or change of instrument indication to a change in the value of the quantity being measured. It denotes the smallest change in the measured variable to which the instrument responds.
• Deflection factor or inverse sensitivity is the reciprocal of sensitivity.

Accuracy: 

• Accuracy is the degree of agreement of the measured dimension with its true magnitude. 
• It can also be defined as the maximum amount by which the result differs from the true value.

Consistency: 

• When successive readings of the measured quantity obtained from the measuring instrument are the same all the time, the equipment is said to be consistent.

Range:

• The range is defined as the lower and upper limit that an instrument can measure a value or signal such as Amp, Volt, Ohm etc.
