3 - Language Dictionary Measurement Subsystem (Current) This subsystem programs the current measurement capability of the ac source. Two measurement commands are available: MEASure and FETCh. MEASure triggers the acquisition of new measurement data before returning a reading. FETCh returns a reading computed from previously acquired data. Individual outputs of a three-phase source are specified by the setting of INSTrument:NSELect.
