Test instruments such as oscilloscopes and DMMs (digital multimeters) often let you get the measurement results you need with just the press of a button. But the number on a meter's display or the ...

This technical note explores the sources of error in gravimetric measurements used for aerosol photometer calibration, emphasizing the impact of discrepancies in ...

A “standard reference thermoelectric module (SRTEM)*” for objectively measuring thermoelectric module performance has been ...

• Force vectors don’t want to remain in line with the object being pushed. • Load-cell specifications usually do not call out accuracy, but rather linearity, repeatability, and hysteresis. • Accuracy ...

The importance of calibration for all electronic test equipment. The main reason why such equipment must be regularly calibrated. The pros and cons of self-calibration or using outside services. It’s ...

The input offset voltage (V OS) of an operational amplifier (op amp) is modeled as a DC error source that acts like a voltage source on the noninverting input. It can ...

Metrology is the science of precise measurement. It ensures accuracy and consistency across scientific, industrial, and engineering fields. Calibration is the process of aligning measurement ...

A calibration error in 4,001 alcohol cases resulted in inaccurate records in some of them, drawing criticism from defense attorneys, and forcing prosecutors to take a ...
