Product design
The T&M F series is a terminating shunt with a flange input. Plan its connection around the current circuit and fixed support. Check body dimensions, the mounting flange and cooling conditions as well as the required electrical response.
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.
