• TRUE

• FALSE

If the calibrated instruments and sensors are utilized in identical environmental conditions to those under which they were not calibrated, calibration ensures that the measuring accuracy of all instruments and sensors employed in a measurement system is known over the whole measurement range.

• TRUE

• FALSE

Instrument calibration has to be __ at prescribed intervals because the characteristics of any instrument change over a period.

Determination of the frequency at which instruments should be calibrated is independent of several factors that require specialist knowledge.

• TRUE

• FALSE

A proper course of action must be defined that describes the procedures to be followed when instrument is found to be out of calibration.

• TRUE

• FALSE

Give two examples of Control of Calibration Environment.
