QUIZ 2

It is the process of comparing a measurement device or instrument with known standard to determine its accuracy and adjust it if necessary.

(a)  

The purpose of calibration is to ensure that the measurement device or instrument provides accurate and reliable measurements.

• 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 (a)   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.

THIS WILL ENABLE BETTER ENVIRONMENTAL CONTROL TO BE APPLIED IN THE CALIBRATION AREA AND WILL ALSO OFFER BETTER PROTECTION AGAINST UNAUTHORIZED HANDLING OR USE OF CALIBRATION INSTRUMENTS.

(a)  

The calibration facilities provided within the instrumentation department of a company provide the first link in the (a)   .

The instrument used for calibrating working standard instruments is known as a secondary reference standard.

• TRUE

• FALSE
