| 1.75 | input quantity in a measurement model | ||
| input quantity | |||
| Quantity that must be measured, or a quantity, the value of which can be otherwise obtained, in order to calculate a measured quantity value of a measurand. | |||
| Example: | When the length of a steel rod at a specified temperature is the measurand, the actual temperature, the length at that actual temperature, and the linear thermal expansion coefficient of the rod are input quantities in a measurement model. | ||
| Note 1: | An input quantity in a measurement model is often an output quantity of a measuring system. | ||
| Note 2: | Indications, corrections, and influence quantities can be input quantities in a measurement model. | ||
