It is important the belleville washers are installed in the configuration shown in Figure 1-22. 4b Place the screw support bracket in front of the carriage screw. The two threaded holes in the bracket should face the two matching holes in the carriage. Loosely install the two 1/4 x 1/2-inch button-head screws. 4c Before tightening the screws, apply some pressure to the bracket to compress the belleville washers. The handle should still turn freely, but the turning force should now be around five to six pounds. To adjust the force needed to turn the crank handle, adjust the compression of the belleville washers. 4d Using a 5/32-inch allen wrench, tighten the two button-head screws.

Torque Module Installation and User Guide for Model 250i Dynamometers 2-1 CHAPTER 2 Torque Cell Calibration TORQUE CELL CALIBRATION ................................... The Torque Module 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. 1 2 Verify you are in the MakeRun screen. 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/manuals.shtml) 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. Figure 2-1: Zero Calibration Window 2-2 Torque Module Installation and User Guide for Model 250i Dynamometers U S I N G T H E TO R Q U E M O D U L E Torque Cell Calibration Once the Zero Calibration is complete, the Calibration Mass window will appear. 5 Enter the Torque Module calibration value. Refer to Figure 2-3. Note: You must perform this step the first time you calibrate the load cell. Or If you are only performing a Zero Calibration, click Finish. Figure 2-2: Calibration Mass Window Enter the calibration number stamped near the bolt pattern at the end of the calibration arm. If you do not have enough room to use the bolt pattern closest to the end of the calibration arm, use the number stamped near the bolt pattern in the center of the arm.

Note: The Torque Gauge may or may not be in this range. • If the torque cell has been previously calibrated incorrectly or has not been calibrated for a while, the gauge may show values out of this range until calibration is complete. • If you use the bolt pattern in the center of the calibration arm, the gauge will show values around 250-260 foot-pounds. Note: Let the torque gauge needle stabilize before clicking Next. 9 From the Span Calibration window (Figure 2-4), click Next to continue. At this point, the value on the gauge should match the value on the calibration arm. 10 Remove the calibration arm and weights and click Finish.
