English - English
the property or quality of being repeatable
the variation amongst multiple measurements taken under the same conditions
The ability of a transducer to reproduce output readings when the same measured value is applied to it consecutively, under the same conditions, and in the same direction Repeatability is expressed as the maximum difference between output readings as a percent of full scale
The total error that the measurement system will possibly add to the measurement Components of repeatability include, but are not limited to, (depending on the system) resolution, timebase accuracy, trigger jitter, quantization noise, aliasing, interpolation and operator/environmental effects Any result presented by a measurement system can be thought of as the sum of the actual jitter of the device "+" the repeatability of the measurement system
The closeness of agreement among a number of consecutive output values measuring the same input value under the same operating conditions, approaching from the same direction Usually measured as nonrepeatability but expressed as repeatability, a percentage of span
The ability of an instrument to measure the same input to the same value over a short period of time and over a narrow temperature range
A statistical term associated with accuracy describing how nearly a value is repeated It is the deviation from the average difference between the expected value and erroneous values For example, a measuring system may be very inaccurate, but if the erroneous readings are always exactly the same, it has high repeatability On the other hand, even if a number of readings average out close to the desired value, the repeatability might be low if there were many high and low readings
{i} ability to be repeated, ability to be done again
- the measurement of the spread around a test result from a single analyst and/or single analyzer at the same site on the same sample However, this does not mean that the result is accurate (produces the true value)
The ability of a device to produce the same output reading when subject to same input applied consecutively over a short period of time (also called precision) Sometimes used to signify device to device variation in parameter
The ability of a meter to measure the same input to the same value over a short period of time and over a narrow temperature range
A measure of how often a method converges on the same solution (not necessarily the correct solution) with a given amount of data
The ability of an instrument to repeat an output when given the same input For a motion system this is the ability to achieve a commanded position at different times For a sensor this is the ability to produce the same output signal, when the input signal is applied repeatedly
The ability of a machine to perform the same operation any number of times to a specified degree of accuracy
- The ability of a transducer or readout instrument to reproduce readings when the same input is applied repeatedly
The ability of the switch to actuate repeatedly at the desired set point within sensor tolerance
The consistency in which a system moves to a commanded position Numerically, it is defined as the range of positions attained when the system is repeatedly commanded to a location under identical motion and load conditions Uni-directional repeatability, which is measured by repeatedly positioning in the same direction, may ignore the effects of backlash or hysterisis within the system The more stringent bi-directional repeatability specification measures the ability to return to a commanded position from opposite directions
The specification of how accurately a manipulator can return to a "taught point" For instance: once a manipulator is manually placed in a particular location and this location is resolved by the robot, the repeatability specifies how accurately the manipulator can return to that exact location Of course, the finer the degree of resolution within the robot determines the repeatability See Teach, and Accuracy
The ability of a pressure switch to repetitively operate at its setpoints For example, if a pressure switch set to actuate at 200 psi repeatedly actuates from 199 to 201 psi, it is considered to be repeatable within plus or minus 1%
The closeness of agreement among a number of consecutive measurements of the output for the same value of the measured signal under the same operating conditions, approaching from the same direction, for full range traverses
The ability of a transducer or readout instrument to reproduce readings when the same input is applied repeatedly
The degree to which repeated measurements of the same quantity vary about their mean
The ability of an instrument to give the same reading under repeated identical conditions
the degree of agreement between mutually independent test results produced by the same analyst using the same test method and equipment on random aliquots of the same sample within a short period of time
The ability of an instrument to reproduce output readings when the same pressure value is applied repeatedly, under the same conditions, and in the same direction
The degree of agreement between a sensor's output values in response to the same input value when this same input condition is presented multiple times The repeatability is usually expressed as a percentage of full scale range (i e 1% repeatability)
The closeness of agreement among measurements of the same variable, repeated under the same conditions, especially when changes in conditions occur or when operation is interrupted between the measurements
The ability to display the same value when a weight is placed on a scale more than one time Often expressed as a standard deviation of 5 to 10 tests Also called reproducibility
