Generally, all specifications are valid at the stated operating and
measurement conditions and settings, with uninterrupted line voltage.
Describes warranted product performance that is valid under the specified
conditions.
Specifications include guard bands to account for the expected statistical
performance distribution, measurement uncertainties changes in
performance due to environmental changes and aging of components.
Characteristics describe the product performance that is usually met but
not guaranteed. Typical values are based on data from a representative set
of instruments.
Give additional information for using the instrument. These are general
descriptive terms that do not imply a level of performance.
