BMX Transducer Operation Instructions
Rev 1.0
Calibration Procedures
1. Attach the BMX securely to a work surface with the cable connector toward the top so that the axis of tool rotation is
parallel to the ground.
2. Connect the BMX to a torque analyzer/display. Review the torque range of the transducer and select the appropriate
measurement units.
3. Determine type of calibration to be performed.
Calibration at 3 Pts.
Test at 10%, 50% and 100 of Full Scale.
Calibration at 6 Pts.
Test at 10%, 20%, 40%, 60% 80% and 100 of Full Scale.
Direction
Clockwise and/or Counter Clockwise
4. Select the appropriate Calibration Arm or Wheel. Attach it to the input drive of the BMX.
5. Gently connect the Hanger to the Calibration Arm or wheel.
6. Load 3 times to minimum 80% FS in direction of operation and reset to zero after loading.
7. Apply series of increasing torques in direction of operation starting from the lowest test point.
8. Record readings from the test device at each test point prior to performing any adjustments.
9. Repeat steps 6-8 in the opposite direction (if required).
10. Perform calibration adjustments. Repeat test as described above until readings at all test points are within tolerances.
11. Repeat test as described above and record 5 readings from test device at each test point. Compile all necessary details
to generate test report.
12. Remove old calibration label and place new label on transducer.
