Don�t heap all the blame for a wrong measurement on the DMM. There can be several less obvious sources of the errors. Testing assemblies and components usually includes checking the continuity of ...

Several years ago, I wrote about possible sources of measurement errors in testing one’s blood pressure (see Avoiding blood pressure measurement errors). Since then, I have kept a very careful record ...

Very often, in the test and measurement industry, a measurement is made by instrumentation, which is often subject to errors. It is difficult to estimate the true value of the measured quantity given ...

In order to measure the mechanical properties of materials in compression, tension, bending or torsion, a universal testing machine is utilized. This article outlines the two different types ...

Acting like an "invisible lens," it causes signals to bend slightly and lag in the atmosphere, thereby affecting measurement accuracy. Accurately modeling and forecasting this delay has become an ...

A study has made it possible to estimate experimentally the energy required to transfer protons from water to ionic liquids. Researchers have for the first time determined the acidity of ionic liquids ...
