Product design
The T&M R series combines a flange current input with a coaxial signal output. Plan the body, support and cooling space together, then route the receiving instrument cable so that it does not obstruct installation or maintenance.
Measurement and application
A shunt converts current into a voltage signal for measurement equipment. Selection involves its position in the current path as well as the arrangement of the voltage sensing connections.
Selection and connections
Consider whether the task involves continuous operation or pulse testing, then confirm mounting, connection space and instrument interface. Sensing connections, thermal conditions and circuit layout should follow the instructions for the chosen model.
