AUTO 1 - PRINCIPLES OF CALIBRATION

In calibration, Error can be defined as:

• the difference between the setpoint and the process value

• the calibration mistakes committed by the calibrator

• the result of measurement minus the true value of the measurand

• when the instrument readings go out of range

In calibration, Reference Standard can be defined as

• the standard that assess and monitors quality

• the standard that is used as reference

• the reference used in many quality standards

• measurement standard having the highest metrological quality available in the organization

During the conduct of calibration, the calibration personnel make the following assumptions, EXCEPT

• the instrument being calibrated is accurate

• handling procedures are consistent

• test item and reference standards respond in the same manner in the test environment

• calibration is repeatable, yielding same results

Most transmitter calibration are done in a five points calibration. What is the output span of this calibration

• 0 – 40 mA

• 0 – 20 mA

• 4 – 20 mA

• 5 – 25 mA

In calibration, ___________ is defined as dispersion of values that can be attributed to the measurand

• uncertainty measurement

• reference standard

• errors

• calibration

A documented, verified, and validated process that describes a set of operations in accordance to a given method.

• calibration procedure

• calibration steps

• calibration process

• reference

Calibration labels need to conform _________

• ISO/IEC 17025

• ISO 14001

• IEC 3652

• ISO 9001

Measured value + Bias + Error

• Ideal Value

• reference value

• calibrated value

• all of the choices

Ideal measured value − Ideal reference value

• Deficiency

• Sufficiency

• Error

• tolerance

SOme of these information must appear on calibration labels except:

• calibrate date

• calibrated by

• calibration due

• approved by
