SENSITIVITY is defined as the ratio of the magnitude of the output response to that of input response. STATIC ERROR: It is defined as the difference between the measured value and true value of the quantity. is specified in terms of scale readings over a given period of time. Reproducibility is an undesirable quality in industrial instruments because it is rarely apparent and Drift cannot be maintained. It is classified as Zero drift Span drift or sensitivity drift Zonal drift. Noise spurious current or voltage extraneous to the current or voltage of interest in an A electrical or electronic circuit is called noise. 12. Dynamic Characteristics of Measurement System of response Measuring lag Fidelity Dynamic error OF RESPONSE: It is defined as the rapidity with which a measurement SPEED system responds to changes in measured quantity. It is one of the dynamic characteristics of a measurement system. It is defined as the degree to which a measurement system indicates FIDELITY: changes in the measured quantity without any dynamic error. Dynamic Error is the difference between the true value of the quantity changing with time and the It value indicated by the measurement system if no static error is assumed. It is also called measurement error. It is one the dynamic characteristics.
