What does "calibrating an instrument" mean?
Expert Solution & Answer
To determine
The meaning of 'Calibrating an instrument'.
Explanation of Solution
Calibration is a process in which the accuracy of an instrument is compared with a known standard values. Even if the instrument is perfectly calibrated, after using for a certain period of time and being exposed to moisture and vibration causes stress in it.
For example; if the speedometer of an automobile is actually travelling at a speed of 60 mph but shows a reading of 55 mph it shows the speedometer is not properly calibrated. Now, if the circuits and sensors are so adjusted that it records correct readings then, the instrument is said to be calibrated. So, it is necessary to calibrate the instrument after certain time periods to get the precise results.
There are some instruments that can be easily calibrated, some is calibrated by precise technicians only and there are also some instruments that cannot be calibrated at all.
