This chapter describes the electrical measuring instruments and measurements. Tests and measurements are important in designing, evaluating, maintaining, and servicing electrical circuits and equipment. To detect electrical quantities such as current, voltage, resistance, or power, it is necessary to ...

The basics of electrical instruments and measurements (theory and applications) Constructionally, the two are similar that the control spring and the pointer of the watt-meter are replaced, in the case of watthour meter, by a brake magnet and by a spindle of the meter. The bra...
Known solutions within the field of the measurement of partial discharge pulses for diagnostic purposes provide for the use of peak detector instruments, which are not able to measure all information useful for a diagnosis of the electrical system, and oscilloscopes interacting with a computer, ...
Measurements were taken in a biosafety cabinet after stopping fluid flow. A CultureTemp 37 °C warming plate (SP Bel-Art) was used to minimizing cooling of the culture medium during measurement. Prior to collagen coating and cell seeding, the blank resistance of each device was measured (...
Dr. Norman Campbell alone in recent years seems to have felt the necessity of maintaining a close and direct connexion between the principles and experi- mental laws which he enunciates as the basis of our measurements, and the methods that we actually employ in our everyday work. His work ...
Organic materials exhibit higher nonlinear optical efficiency than those of inorganic materials owing to their smaller refractive index, high degree of delocalization, fast and large nonlinear response, low mobility, large band gap and higher laser damage threshold. This large second order nonlinearity ...
Gross Errors: Gross errors are human mistakes in reading or recording measurements, which can be reduced by careful procedures and multiple experimenters. Systematic Errors: Systematic errors are consistent inaccuracies due to faulty instruments, environmental conditions, or observational mistakes. ...
