■ Minimum measurable value (or threshold)) This the smallest measurable value. defined minimum measurable value and a maximum measurable value ■ Rated calibre An instrument's calibre the value the quantity measured which corresponds the upper limit the measurement range. For instrument providing good conversion linearity, may equal the resolution. ■ Resolution This the smallest measurable difference value. ■ Root-mean-square value signal This the value the (positive) signal producing the same heating when passes through specified resistance. An AVG-type instrument only capable giving correct results for pure sinusoidal signals. For example, for ammeter, the upper limit the range its calibre A. also the value measurement count quantification unit, usually called the "unit".MULTIMETERS Theoretical Introduction Multimeters A few definitions: ■ Measurement range This represents the limits within which the digital instrument performs specified that the results are not subject to rate error which higher than the maximum tolerated.
