9. Allow the output voltage to settle (~1min) and take the voltage reading.
10. Use the load cell calibration factor to obtain the force applied by the clip.
An example measurement follows:
Initial reading:
Final reading:
Load cell calibration factor:
(129.4 – 34.5) / 1.29 = 73.6 lb
46
Preliminary Information
