Performed by comparing the nominal value of the current, of the voltage and of the resistance of multimeters, contrasting the value set on the instrument in calibration with an ACCREDIA (LAT) certified higher class sample instrument.

CALIBRATION OF CURRENT CLAMPS AND OTHER INSTRUMENTS

Performed by comparing the nominal value of the current, of the voltage, of current clamps' resistance and of all measuring instruments detecting an electrical quantity, by contrasting the value set on the instrument being calibrated with an ACCREDIA certified higher class sample instrument (LAT).
