The Keysight 34470A is a 7.5-digit benchtop digital multimeter engineered for precision measurement across voltage, current, resistance, frequency, and specialized functions. Leveraging Truevolt technology—a patented analog-to-digital converter architecture—the instrument eliminates measurement errors from noise and injected current while maintaining metrology-grade accuracy guaranteed to ISO/IEC 17025 standards. It delivers 16 ppm basic DC voltage accuracy and reads up to 50,000 samples per second, making it suitable for demanding production, service, and research environments.
