Analogue Measuring Instruments

ANALOGUE MEASURING INSTRUMENTS Analogue instruments register a value to be measured and show it on an analogue display, usually by a pointer on a scale. So the value is displayed in a stepless and continuous way. In opposition to digital displays, instabilities and tendencies of a value can be recognized faster and more intuitively on an analogue display. On the other hand at analogue displays exact numerical values are more difficult to read compared to a digital instrument (reading error). Analogue instruments are on hand for a broad band of electrical values. They are available in the standardized...
