Linearity in instrumentation
Nettet24. sep. 2024 · Sensitivity = 30.5 uV × 1.36 LSB rms = 41.5 uV rms Gain Error: 0.024% × 200mV = ±48uV Offset Error = ±245uV Linearity Error = 0.0076% of range = 76uV Total Error = 48uV + 245uV + 76uV = 369uV Therefore a 200 mV reading could fall within a range of 199.631 mV to 200.369 mV.

Does output change in direct proportion to a change in input. Let’s say you want to boil a gallon of water to make spaghetti, so you put a big pot on the stove. For the sake of this discussion, you have a thermometer in the pot so ...
Linearity in instrumentation
Did you know?
NettetSome instruments provide means to adjust the linearity of their response, in which case this adjustment needs to be carefully altered. The behavior of a linearity adjustment is unique to each model of instrument, and so you must consult the manufacturer’s documentation for details on how and why the linearity adjustment works. NettetWhat does linearity mean? Linearity reflects the ability of a sensor to respond to changes in a measured variable in the same way across the full range. If you’ve …
NettetHowever, this technique cannot reduce the affects of non-linearity, and the noise must have a Gaussian distribution. Sensitivity Consider a measurement device that has a ±1.0 volt input range and ±4 counts of noise, if the A/D converter resolution is 2 12 the peak-to-peak sensitivity will be ±4 counts × (2 ÷ 4096) or ±1.9 mV p-p. NettetLinear and Non-Linear Control System. A control system is a group of equipment that manages, orders, guides, or controls the actions of other devices in order to produce a specific outcome. To put it another way, a control system can be defined as a system that directs other systems to reach a specific state.

B) (英文) NettetSensitivity to departure from linearity: If $$ l_{lower} \le W \le l_{upper} $$ the instrument is in statistical control. Statistical control in this context implies not only that measurements are repeatable within certain limits but also that instrument response remains linear. The test is sensitive to departures from linearity.
NettetThe linear range is determined by testing specimens with defined concentrations. Linearity standards can be purchased from the instrument manufacturer, Maine Standards Company LLC, or the College of American Pathology (CAP). Ideally, standards should be suspended in the same matrix as patient samples.
