Calibration of devices cannot be done without a standard. What is a standard?
- A Another measurement device of known accuracy
- B Another measurement device for correcting malfunction
- C A device for reading physical properties of instruments
- D A measurement device for adjusting alignments
That's Correct!
It's Wrong!
A standard is another measurement device of known accuracy. It serves as a reference point or benchmark against which the accuracy of other devices can be compared and calibrated. By comparing the measurements taken by the device being calibrated with those taken by the standard, any discrepancies or errors can be identified and corrected. The standard provides a reliable and consistent basis for ensuring the accuracy and reliability of measurement devices.
