An instrument has been used to measure the length of a part. The result was 6.70052 cm. An error-of-measurement study on the instrument had the following results: Bias: +0.00254 cm (on the average, the instrument reads 0.00254 cm high). Repeatability (precision): 0.001016 cm (1σ). Make a statement concerning the true value of the part just measured. State all assumptions needed.

The output of a potentiometer is measured by a voltmeter having a resistance Rm, as shown in Figure 3.12. R, is the resistance of the total length X, of the potentiometer and R, is the resistance between the wiper and common point for a general wiper position X/. Show that the measurement error due to the resistance R of the measuring instrument is given by R (R-R;) Error = E R.(R;R + R„R, -R) Hence show that the maximum error...

Lastly we will look at how uncertainty relates to measurement, precision and Laboratory # 2 : Measurement and UncertaintyY Introduction semester. We will also examine the use of dimensional analysis and significant figures in performing accuracy. Precision Scientific measurements should be as precise as possible: this means that every measurement will include one uncertain or estimated digit. The number...
