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 ...

When gathering a measurement using a spectroscopy instrument, the user wants to be confident in the result. Whether the technique is OES, XRF, or LIBS, or if thickness or composition are measured, the ...

Systematic errors are caused by defective parts like incorrectly adjusted optics or interfering influences such as a dirty light path, and can lead to measurement result deviation from the real value.

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 ...

This article discusses simple processes for addressing the random and systematic errors caused by the dead time in a gramma-ray spectrometer. It also explains the applicability of the livetime clock ...

Developing a method is an important part of planning an investigation. In an experiment, evaluate the validity of the steps leading up to the conclusion for it to be valid. Random and systematic ...

Raised intraocular pressure (IOP) increases the risk of glaucoma. Eye-care professionals measure IOP to screen for ocular hypertension (OHT) (IOP>21 mm Hg) and to monitor glaucoma treatment.

GPS receivers must deal with measurements and models that have some degree of error, which gets propagated into the position solution. If the errors are systematically different for the different ...
