false alarm: Alarm not caused by a radioactive source under the specified background conditions.
functional check: A frequently used qualitative check to determine that an instrument is operational and capable of performing its intendcd function.
NOTE—Checks may include, for example, battery check. iem setting. or radioactive source response check. indicated value: (A) A scale or decade reading. (B) The displayed value of the readout, See also: rcading
indication: Displayed signal from the instrument to the user conveying information such as scale or decade, status, malfunction, or other critical information.
influence quantity: Quantity that may affect the result of a measurement without being the subject of the measurement.
instrument: A complete system consisting of one or more assemblies designed to quantify one or more characteristics of ionizing radiation or radioactive material.
monitoring: Means provided to continuously indicate the state or condition of a system or assembly. NOTE— Monitoring may also be used for the real-time measurement of radioactivity or radiation levels.
Os er-range response: The response of an instrument when exposed to radiation intensities greater than the upper detection limit,
performance test: An evaluation of the performance of an instrument in response to a given influence quantity,
point of nieasurenient: Place where the conventionally true values are determined and where the reference point of the instrument is placed for test purposes.
range: All measured values between the minimum statistically quantifiable instrument response (or reading) and the maximum level at which the instrument meets the required accuracy.
reading: The indicated or displayed value of the readout.
readout: The portion of the instrument that provides a visual numerical or other quantitative display of the response of the detector to radiation.
reference point of an instrument: Location within an instrument to be placed at the point of measurement. The reference point may he indicated by a physical mark or marks on the outside of the instrument. Its position may be clearly identifiable from the construction of the instrument or described in the instrument manual.
restricted mode: An advanced operating mode that can be accessed by an expert user (e.g., via password) to control the parameters that can affect the result of a measurement (i.e., radionuclide library, routine function control, calibration parameters, alarm thresholds).
NOTE- Restricted mode may be called the“advanced” or“expert” mode.
spurious indications: unexpected changes in the instrument response such as display changes (e.g., display going blank, part of the display not fully working), instrument switches off a sudden increase in the instrument displayed readings, or modifications to the instrument settings.IEEE N42.32 pdf free download.
