LOAD CELL CALIBRATION
This section provides instructions for calibrating the load cell(s). The load cell must
be calibrated prior to use. Follow the directions on the screen exactly. Failure to
perform the directions accurately will result in improper torque values.
Note: Repeat these steps for each eddy current brake.
You will need the following parts:
• 35430899 Weight (4)
• 61319001 Calibration Arm Assembly
1 Verify you are in the MakeRun screen.
2 Verify you are connected to the dyno electronics.
Note: For more information on connecting to the dyno electronics, refer to the
WinPEP 7 User Guide (on your WinPEP CD or at www.dynojet.com) or the
WinPEP 7 Online Help.
3 Select Tools  MakeRun Options  Torque Cell Calibration.
Note: Before proceeding, be sure the eddy current brake is free and clear of any
obstructions. There should not be anything resting on the eddy current brake or
the dynamometer drum during this procedure.
4 Click Next to perform the Zero Calibration.
The Calibration window will appear. The hardware is now zeroing out the torque
cell. If the unit does not calibrate, recheck the setup and retry.
