When describing the measurement characteristics of measuring instruments, the national metrological technical specification JJF 1001-1998 should be used.
Terms defined by the terms and definitions.
The terms and definitions used in this specification are consistent with JJF 1001-1998 General Terms and Definitions.
3.1 measuring instrument measuringinstrument
measuring tools
An appliance for measuring, either alone or in conjunction with an auxiliary device.
3.2 physical measurement materialmeasure
An appliance that reproduces or provides a given amount of one or more known values in a fixed form when in use.
Example. a) weight;
