How can the precision of a measuring instrument be increased?

Answer 1

Since I already answered your accuracy question, I think you should do the rest of your homework yourself.

G'day lilnea20022006,

Thank you for your question.

Calibration increases the precision of measuring instruments.

Calibration refers to the process of determining the relation between the output (or response) of a measuring instrument to the value of the input quantity or attribute, a measurement standard. In non-specialized use, calibration is often regarded as including the process of adjusting the output or indication on a measurement instrument to agree with value of the applied standard, within a specified accuracy. For example, a thermometer could be calibrated so the error of indication or the correction is determined, and adjusted (e.g. via calibration constants) so that it shows the true temperature in Celsius at specific points on the scale.

In the United States, the National Institute of Standards and Technology, a part of the federal government, maintains standards and is considered the arbiter and ultimate (in the U.S.) authority for values of SI units and industrial standards. NIST also provides traceability to its standards by calibration, by which an instrument's accuracy is established by comparing, in an unbroken chain, to higher level standards, e.g. the standards maintained by NIST. For each step in the process, the measurement uncertainty is evaluated.

I have attached sources for your reference.

Answer 3

You will get back the original accuracy by calibration but you cannot increase the precision it was already optimise by manufacturer.

Answer 4

Umm, no. It's set to the precision it will be when manufactured. It can be calibrated to be more accurate however.

Answer 5

calibration, the actual process changes for different instruments
