The calibration hierarchy helps us to record the sequence of calibrations performed on an instrument from a reference standard to the final measuring system.
Accuracy is how close a value to its True Value. Precision is how repeatable a measurement is. Learn the difference between them with examples.

Both soft starter and VFD can start and stop the motor but the main difference is VFD can do the speed control of motor also.
A megger is used to measure insulation resistance and it is powered by a DC generator or battery of a higher voltage range.
Calibration plays an important role in quality control. If an instrument is not calibrated we may suffer loss of our health, money or safety.
Any measurement has two parts – a number and a unit of measurement. The unit of measurement is very important in calibration.
A memristor controls the flow of current in a circuit and also remembers the amount of charge that has previously flowed through it.
We compare the reading of Unit Under Calibration (UUC) with reference to Master Instrument. Therefore the selection is very important.
