A. range
B. overshoot
C. span
D. error
View Answer
Ans : B
Explanation: The amount of output measured beyond the final steady output value in response to a step change in the measurand is called overshoot and range is the measurand values over which a measuring device is intended to measure, specified by upper or lower limits.
Question 2
____________ is the maximum deviation of any calibration point, obtained for either increasing or decreasing input, obtained for either increasing or decreasing input, from the best fit straight line having overall minimum deviation.
A. Linearity
B. Rise time
C. span
D. error
View Answer
Ans : A
Explanation: Linearity is the maximum deviation of any calibration point, obtained for either increasing or decreasing input, obtained for either increasing or decreasing input, from the best fit straight line having overall minimum deviation and rise time is the time required for the output of a measuring device to rise from 10% to 90% of its final value and span is the algebraic difference between the maximum and minimum limits of the range.
Question 3
____________ is the maximum difference in output for the same measurand value within the range of a measuring device, one obtained by increasing from zero and other by decreasing from a higher value of the measurand.
A. Linearity
B. Hysteresis

D. None of the above
View Answer
Ans : B
Explanation: Hysteresis is the maximum difference in output for the same measurand value within the range of a measuring device, one obtained by increasing from zero and other by decreasing from a higher value of the measurand and linearity is the maximum deviation of any calibration point, obtained for either increasing or decreasing input, obtained for either increasing or decreasing input, from the best fit straight line having overall minimum deviation.
Question 4
The algebraic difference between the indicated or observed value and the true value of the measurand is the ______________
A. range
B. overshoot
C. span
D. error
View Answer
Ans : D
Explanation: The algebraic difference between the indicated or observed value and the true value of the measurand is the error and the amount of output measured beyond the final steady output value in response to a step change in the measurand is called overshoot.
Question 5

A. range
B. drift
C. overshoot
D. error
View Answer
Ans : B
Explanation: The random changes in output under constant measurand and normal operating conditions is called the drift and The algebraic difference between the indicated or observed value and the true value of the measurand is called the error.
Question 6

A. Linearity
B. Hysteresis
C. Calibration
D. Drift
View Answer
Ans : C
Explanation: Calibration is a test during which standard values of measurand are applied to the measuring device and the corresponding output readings are compared with the standard values
Question 7
________________ is the time during which a device or system is insensitive, after receiving a stimulus, to any other impulse or stimulus.
A. Dead time
B. Hysteresis
C. Calibration
D. Linearity
View Answer
Ans : A
Explanation: Dead time is the time during which a device or system is insensitive, after receiving a stimulus, to any other impulse or stimulus
Question 8
______________ is the utilization of supplemental device, materials, or processes to minimize known sources or error.
A. Dead time
B. Compensation
C. Calibration
D. Linearity
View Answer
Ans : B
Explanation: Compensation is the utilization of supplemental device, materials, or processes to minimize known sources or error while dead time is the time during which a device or system is insensitive, after receiving a stimulus, to any other impulse or stimulus while calibration is a test during which standard values of measurand are applied to the measuring device and the corresponding output readings are compared with the standard values.
Question 9
A calibration during which the measurement varies with time in a specified manner and the output is recorded as a function of time is called ______________
A. dynamic calibration
B. drift
C. error
D. dynamic characteristics
View Answer
Ans : A
Explanation: A calibration during which the measurement varies with time in a specified manner and the output is recorded as a function of time is called dynamic calibration while he random changes in output under constant measurand and normal operating conditions is called the drift and The algebraic difference between the indicated or observed value and the true value of the measurand is called the error.
Question 10

A. dynamic calibration
B. drift
C. error
D. dynamic characteristics
View Answer
Ans : D
Explanation: Characteristics of a measuring device which relate to its response to variations of the measurand with time are called dynamic characteristics while a calibration during which the measurement varies with time in a specified manner and the output is recorded as a function of time is called dynamic calibration.
