The LR series also includes the LR-19 series for applications where a shorter length and smaller diameter body is required and the spring loaded LRS-18 for applications where the probe cannot be hard fixed to the measurand
The careful definition of the measurand
is essential (11).
For example, what terms are better or "more correct": measurement error or error of measurement; "true value" of the measurand
or simply "value" of the measurand
Measurement, rigorously defined as 'ascertaining the size, amount or degree of a measurand
by instrumental comparison with a standard unit or by indirect calculation based upon theory', is what makes science and technology different to imagination.
The resulting variation in measurand
between routine MPs leads to noncomparability of CDT values and reference intervals/decision limits and, consequently, to difficulty with both result interpretation and understanding of the diagnostic value of CDT.
is the ratio, R, of the detector response for a given radioactive source to that of a NIST radium-226 reference source.
(reference interval) Day 3 Day 4, Day 4, 11:07 AM 11:13 AM pH (7.
Sometimes a combined result of measurement from multiple evaluations of the same measurand
The molecular forms of albumin in urine that define the measurand
are unknown (7, 13).
As the true value of the measurand
on orbit will always be an unknown quantity, the accuracy of the measurement can best be assessed by combining the results from different sensors and calculating the uncertainty of that Combined Reference Value (CRV) based on the individual sensor data (12).
Measurement accuracy is defined by the NCCLS as "the closeness of the agreement between the result of a measurement and a true value of the measurand
