1.
An instrument with a range of 0-10 bar is used for measuring pressure. If the expected value of reading is between 0 and 1 bar then the instrument will give
2.
A voltmeter connected across a resistor gives a value of 65 V but the expected value of resistor was 68 V. Then the absolute error and the relative accuracy of the measurement will be
3.
Precision of an instrument is defined as
4.
An instrument with high precision implies
5.
Low accuracy measurements from a high precision instrument are normally caused by
6.
Which of the following statements are correct I. Repeatability means the closeness of output readings when the same input is applied repetitively over a short period of time, with the same measurement conditions and same instruments. II. Reproducibility means the closeness of output readings for the same input when there are changes in the method of measurement and conditions of measurement.
7.
For an instrument the degree of repeatability or reproducibility in measurements is an alternative way of expressing its
8.
Range or span of an instrument defines
9.
A voltmeter of 0 to 250 V has an error of ± 1% of full scale deflection. If the true voltage of voltmeter is 25 V then the range of its reading is
10.
Four observers recorded a set of current measurement as: 125.09 mA, 125.21 mA, 125.05 mA, 125.14 mA. The range or span of error will be
