In power quality analysis projects, accuracy at low currents is as crucial as at high currents. The Fluke model i40s-PR falls within the category of digital multimeter accessories and network analysis equipment, designed to fill this gap.
This 40-amp clamp allows engineers to accurately log and analyze leakage currents, secondary transformer currents, and small loads with exceptional precision.
A distinct feature of the i40s-PR is its full compatibility with the self-identifying system of the Fluke 1750; upon connection, the device recognizes the probe and automatically adjusts the scaling.
The design of the clamp jaws ensures easy wrapping around thin wires, even in crowded electrical panels. Additionally, phase angle error in this model is minimized, keeping active and reactive power calculations as accurate as possible.
