Analog instruments pdf

Analog instruments are also classified as : 1.Indicating 2.Recording 3.Integrating Indicating instruments are those instruments which indicate the magnitude of a quantity being measured.They generally make use of a dial and a pointer for this purpose.Ordinary voltmeters, ammeters and wattmeters belong to this category. analog instrument such as a ruler as triangular. You may think that another choice might be more realistic. Perhaps you think that Figure 4 is a better approximation, since it makes the probability higher for values that are close to the midpoint value of the measurand than the triangular pdf.
