Calibration is intended to
- A.
  
  Eliminate bias in a device's readings
- B.
  
  Repair broken devices
- C.
  
  Assess calibration technicians
- D.
  
  Process a new device
Correct Answer
A. Eliminate bias in a device's readings

Explanation
Calibration is a process that is performed to eliminate bias in a device's readings. Bias refers to any systematic error or deviation from the true value that occurs consistently in the device's measurements. By calibrating a device, any inaccuracies or biases can be identified and corrected, ensuring that the device provides accurate and reliable readings. Calibration helps to maintain the integrity and precision of the device's measurements, making it an essential process in various fields such as scientific research, manufacturing, and quality control.

The standard instrument for calibrating pressure gauge is
- A.
  
  Oscilloscope
- B.
  
  Dry block temperature tester
- C.
  
  Dead weight tester
- D.
  
  Dry weight tester
Correct Answer
C. Dead weight tester

Explanation
A dead weight tester is the standard instrument used for calibrating pressure gauges. It works by applying a known pressure to the gauge under test using calibrated weights. The pressure is generated by the weights acting on a piston or piston-cylinder assembly, creating a force that is directly proportional to the pressure being measured. This allows for accurate calibration of the pressure gauge. Oscilloscopes are used for measuring and analyzing electrical waveforms, while dry block temperature testers are used for calibrating temperature sensors. Dry weight testers are not a recognized instrument for calibrating pressure gauges.

The SI unit for temperature is
- A.
  
  Kelvin
- B.
  
  Degree Celsius
- C.
  
  Fahrenheit
- D.
  
  Degree Pasteur
Correct Answer
A. Kelvin

Explanation
The SI unit for temperature is Kelvin. Kelvin is the base unit of temperature in the International System of Units (SI). It is named after the Scottish physicist William Thomson, 1st Baron Kelvin. Kelvin is an absolute temperature scale where 0 Kelvin represents absolute zero, the point at which all molecular motion ceases. The Kelvin scale is widely used in scientific and engineering applications, especially in fields such as physics, chemistry, and thermodynamics.
