■High precision, low inductance DC/AC current shunt
A40B precision current shunt set includes 14 low inductance coaxial current shunts, adapters and connectors, and a rugged shipping/storage case. The current shunt is designed for currents from 1 mA to 100 A and allows direct measurements of absolute AC and DC currents as well as transfer measurements of AC/DC currents in standard rooms.
These shunts' excellent resistance stability, self-heating power coefficient, and low temperature coefficient allow them to directly measure currents from DC to 100 kHz with greater accuracy than traditional commercial shunt technology. Accurate measurements can now be performed in a single step, compared to the conventional complex AC/DC transfer method.
