6. Place the retention frame onto the board and align it with the backplate standoffs.
7. Place the heatsink on the load cell assembly.
8. Install clip and tighten screws until the clip is fully installed as shown in Figure 25.

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:
34.5
mV
Final reading:
129.4 mV
Load cell calibration factor:
1.29 mV/lb
(129.4 – 34.5) / 1.29 = 73.6 lb
