calibration interval

calibration interval

the period of time or series of measurements during which calibration can be expected to remain stable within specified and documented limits.

The Techkon ColorEnsure feature, which automatically configures the SpectroDens to match the color measurement settings specified in a job, has been expanded to also include an instrument calibration interval and reminder, as well.
Those components that are introduced within a calibration interval (on a specific instrument using specific reagents), such as repeatability, between-operator, between-run, and between-day imprecision, are equal to the signal random error [[epsilon].sub.i] from these sources divided by the slope of signal vs concentration on the calibration curve at position .
Effect of the Calibration Interval. As the subject's state may change during certain intervals, in this section, the effect of the calibration interval on the classifier performance is explored.
These include a tool for Interval Analysis, which enables users to report quickly on device performance by scientifically analysing historical data and drift to allow informed and qualified calibration interval recommendations (which may be longer than manufacturers' recommendations).
Note that the clock skew is considered to be constant during the calibration interval. At the end of the calibration period, if a resynchronization is triggered (the time has come for the resynchronization), the node exchange timestamps with the reference (green area).
Determine your calibration interval by checking TMDE's TB 43-180, Calibration and Repair Requirements for the Maintenance of Army Materiel.
Normally, conductivity sensors are not subject to much wear and the calibration interval according to the DIN EN 27888 standard is half a year.
The sensor's stability results in an extended calibration interval of 12 months, reducing calibration time and maintenance costs.
For example, if testing is done at a time of year that provides a significantly varying temperature range over the antenna calibration interval, the heating or cooling of the cable can introduce errors.
Students may further like to integrate measurements of the UV irradiance measured over the calibration interval (Table 1) using different techniques to obtain more accurate estimates of the exposure for each dosimeter.
If and when "before" calibration data reveals that the chart recorder or data logger has stayed acceptably close to the stated accuracy of the instrument then you can continue to stretch the original calibration interval. Eventually you will find the time period that does have significant effect on the accuracy of your unit.
* Lower maintenance costs with a 2-year calibration interval.
