A calibration error in an instrument measuring sewage levels in the Stanley Park shaft of the city’s massive new $232-million Combined Sewage Storage Tunnel led to ...

• 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 ...

Making accurate delta-time measurements can be difficult, especially when trying to measure jitter. To ensure accuracy, you need to understand the various types of delta-time measurements, as well as ...

Calibration always seems to be scheduled at the most critical time in a project. For example, assume that a piece of test equipment is on a six-month calibration cycle. At month five, the design ...

Instrument calibration should never be taken for granted, and thermal mass flowmeters are no exception. Flowmeters can be built with the highest safety ratings, features, and functions and the most ...

It is a stringent requirement for all quality systems to calibrate the equipment used for measurements. The International Vocabulary of Metrology defines the term calibration as an “operation that, ...

A cobalt unit for teletherapy at a hospital in Ohio was initially calibrated correctly. During the period 1974-1976 the physicist failed to perform regular measurements (calibrations and QA), but ...

New research shows that X-ray photoelectron spectroscopy (XPS) can give misleading analysis results due to an erroneous assumption during calibration. X-ray photoelectron spectroscopy (XPS) is often ...
