73202 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.
Features- Compact size, ideal for carrying
- Large display for easy viewing
- Safe design allows measurement in excess of 20 A (excluding 73204)
- Special model for voltage measurement (73204)
- Simple auto hold function
- Capacitors can be checked (73202/73203)
