73203 Digital Multimeter
Brand: Yokogawa Electric CorporationDigital multimeters (DMMs) employ an A/D converter with a dual-integration system, which determines the measurement value by converting the input voltage into time using an integration AD converter.
The interval to perform an integral action periodically is referred to as the integral action time.
