Dynamometer Torque Calibration Procedure - Multi-Point / Single-Direction for Dyn-Loc V or Inter-Loc V

The flow chart below is to assist with calibrating the torque of an AC dynamometer using a Dyn-Loc V or Inter-Loc V dynamometer controller with the multi-point ⁄ single direction method.
Calibration Assumptions:
  • Weights Are Present
  • Mass of Weights Are Known
  • Operator Has Access to the Calibration Screen of the Dynamometer Controller
  • The Multi-Point Torque Calibration Feature is Enabled within the Dynamometer Controller
  • All Weights and Weight Sets are Configured within the Dynamometer Controller
  • Weight is Hung on the Left Side Calibration Arm (Left vs. Right is Determined by Facing the Dynamometer Side that has been Determined to be the Drive End)
  • If Right Side Calibration is Needed, Substitute "Right" for "Left" in Flowchart
