The PT740-3A is an AC/DC current clamp that enables fast, safe, and simple measurement of all AC/DC currents. Utilizing the Hall effect principle for measurement, it can measure up to 1400A DC and 1400A AC peak. The PT740-3A is also suitable for power measurement and can determine RMS values even in the presence of DC interference. It is fully compatible with oscilloscopes or other instruments with BNC inputs, serving as a high-precision current clamp with a mV-level BNC output. It can be directly connected to display on oscilloscopes or auto-zeroing systems.
