The conditions which must be fulfilled in order to use a measuring instrument correctly, taking account of its design, construction and purpose. NOTE: The conditions of use can refer, among other things, to the type and condition of the subject of the measurement, the value of the quantity measured, the values of the influence quantities, the conditions under which the indications are observed, etc.

EFFECTIVE RANGE

The range of values of the measured quantity for which any single measurement, obtained under specified conditions of use of a measuring instrument, should not be in error by more than a specified amount. NOTE: The effective range may be the whole or a specified part of the interval between the lower and upper range limits. Also known as measuring range, working range
