  • Improved TC
  • Rack and Bench top use
Features & Benefits

The Model 9313A 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 9313A 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 0.02% can be achieved at full power from 5  mΩ to 1 Ω.

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 enclosed in a vented fan cooled enclosure 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 9313A may be used as a Current Shunt or as a set of Standard Resistors for calibrating medium current, low resistance milli ohm meters. The Model 9313A is used in an air environment.
