The Model 9311A Multiple Value DC Current Shunt is the latest development from Measurements International’s series of DC Resistors and Shunts. After many years of research in low value resistance materials, the Model 9311A ensures that you get the best performance on the market today. Combined with MI’s experience in automated measurements at high current levels, accuracies approaching <0.01% can be achieved at full power.
The process selected in treating the element ensures the best performance without introducing self-heating errors with improved temperature coefficients.
The elements are supported on an insulating base for mechanical stability and covered with perforated metal to allow for proper cooling.
Special consideration has been given to the process of curing the elements and reducing the overall temperature coefficient. Optimum surface area dissipates the maximum specified power. The Model 9311A may be used as a Current Shunt or as a set of Standard Resistors. The Model 9311A is used in an air environment.
