Calibration Quiz

What is calibration?

• Comparing measurements to a standard to ensure accuracy

• Measuring an object repeatedly

• Adjusting an instrument to read zero

• Estimating measurements

Which of the following is NOT a reason why calibration is important?

• Ensures accuracy

• Reduces equipment size

• Ensures reliability

• Ensures compliance with regulatory requirements

What type of calibration would be used for a multimeter?

• Mechanical

• Thermal

• Electrical

• Chemical

What is systematic error?

• Error caused by random fluctuations

• Error that affects measurements differently each time

• Error that consistently affects measurements in the same way

• Error that can be corrected by zeroing the instrument

What does random uncertainty in measurement involve?

• Consistent deviation in measurements

• Random fluctuations affecting measurements

• Calibration of the instrument

• Increased resolution of measuring device

Which standard specifies the requirements for the competence of calibration laboratories in Malaysia?

• MS ISO 17025

• MS ISO 9001

• IEC 60601

• ASTM D4169

What is the resolution uncertainty of a measuring device?

• Difference between highest and lowest readings

• Uncertainty due to the device's resolution

• Average of all readings taken

• Total range of measured values

Which organization in Malaysia is responsible for maintaining national measurement standards?

What tolerance is typically associated with a 0-25 mm micrometer?

• ±0.02 mm

• ±0.002 mm

• ±0.05 mm

• ±0.005 mm

What is a bias uncertainty in measurement?

• Error from external factors

• Difference between the mean value and the true value

• Deviation that repeats under the same conditions

• Difference in readings due to environmental changes
