The Agilent 34134A is an AC/DC current probe designed for use with digital multimeters, voltmeters, and other voltage-measuring instruments. The battery-powered clamp-on probe measures low DC or AC current from 10 mA to 50 A DC and up to 40 A AC, allowing current measurements to be taken without breaking the circuit under test. Hall sensor technology senses the magnetic field produced by the current being measured and generates a proportional millivolt DC or AC output signal.

The probe is built for current measurement work in crowded wiring environments. The narrow jaw geometry is designed specifically for optimum use in industrial and automotive applications where space around conductors is limited. Two output ranges are provided: a 1 V/A range (1 mV/mA) for low-current measurements from 10 mA up to 2 A DC or 1.5 A AC, and a 10 mV/A range for higher currents up to 80 A DC or 60 A AC. Range selection is made via a switch on the probe body, with a power indication LED confirming battery operation.

## Brand Heritage

The 34134A originated under Agilent Technologies, which was spun off from Hewlett-Packard in 1999 to house the test and measurement business. In 2014, Agilent's electronic measurement division was separated again to form Keysight Technologies, the current corporate steward of products that originated under the Agilent brand.
