The Keysight 34134A is an AC/DC DMM current probe that extends the current measurement capabilities of compatible digital multimeters without breaking the circuit. Using Hall sensor technology, this battery-powered clamp-on probe measures low DC or AC currents across industrial and automotive applications—ground currents, power supply ripple, and system current distribution. The narrow jaw design accommodates cable diameters to 11.8 mm, making it well-suited for densely wired environments.
