THE EFFECT OF ADJUSTMENT ON MULTIFUNCTION INSTRUMENTS FOR ELECTRICAL METROLOGY: CASE EXAMPLES
Abstract
Top-class multifunction instruments (multimeters and calibrators) implement in their firmware adjustment procedures requiring a minimal set of adjustment standards. The small set of standards' values provided have effects on the (usually very broad) ranges of values and frequencies which the instrument can measure. How errors and uncertainties in the adjustment of specific points affect measurements in such broad ranges has been experimentally investigated in top-class multimeters and calibrators; most interesting results have been observed in the ‘ac voltage’ function; a number of examples are reported.
