26 | 1 | J. Simmons | |
27 | 2 | J. Simmons | * Care must be taken when using the soldering iron, the tip is very hot |
28 | 2 | J. Simmons | * Always wear safety glasses while working with soldering irons |
29 | 2 | J. Simmons | * Avoid breathing in the soldering fumes, use a vent or hood if needed to provide adequate ventilation |

36 | 1 | J. Simmons | |
37 | 3 | J. Simmons | h3. 1. Place sensor on TRRS Audio Connector PCB |
38 | 3 | J. Simmons | |
39 | 3 | J. Simmons | # Place *WSSM-02: TLE4966L Sensor* in jig with label facing “out” (toward window in jig) |
40 | 3 | J. Simmons | # Slide *TLE4966L Sensor* into jig until its label aligns can be seen through the window in jig |
41 | 3 | J. Simmons | # Bend *TLE4966L Sensor* leads down along jig |
42 | 3 | J. Simmons | # Place *TLE4966L Sensor* pins through holes in *WSSM-01: TRRS Audio Connector PCB* with the jack facing up |
43 | 3 | J. Simmons | # Align *TRRS Audio Connector PCB* with lip on jig |
44 | 3 | J. Simmons | # Bend *TLE4966L Sensor* leads over to fix position of sensor relative *TRRS Audio Connector PCB* |
45 | 3 | J. Simmons | # Remove *TLE4966L Sensor/TRRS Audio Connector PCB* sub-assembly from jig |

49 | 4 | J. Simmons | h3. 2. Solder TLE4966L Sensor to TRRS Audio Connector PCB |
50 | 4 | J. Simmons | |
51 | 5 | J. Simmons | # Place *TLE4966L Sensor/TRRS Audio Connector PCB* sub-assembly in helping hands |
52 | 5 | J. Simmons | *Insert Pic* |
53 | 1 | J. Simmons | # Solder all 4 *TLE4966L Sensor* leads to their pins on the *TRRS Audio Connector PCB* |
54 | 5 | J. Simmons | # Trim back excess leads from *TLE4966L Sensor* |
55 | 5 | J. Simmons | *Insert Pic* |
56 | 1 | J. Simmons | |
57 | 1 | J. Simmons | h3. 3. Verify sensor |
58 | 5 | J. Simmons | |
59 | 5 | J. Simmons | # Place *TLE4966L Sensor/TRRS Audio Connector PCB* sub-assembly in *WSSM-03: Sensor Housing Lower Half* |
60 | 5 | J. Simmons | *Insert Pic* |
61 | 5 | J. Simmons | # Connect sensor cable from test stand to *Wheel Speed Sensor* sub-assembly |
62 | 5 | J. Simmons | # Place *Wheel Speed Sensor* sub-assembly in sensor mount on test stand |
63 | 5 | J. Simmons | *Insert Pic* |
64 | 5 | J. Simmons | # Run tests - see test stand for API calls/application used for these tests |
65 | 5 | J. Simmons | ## Verify direction |
66 | 5 | J. Simmons | ### it should report cw when wheel turns 20 rpm cw |
67 | 5 | J. Simmons | ### it should report ccw when wheel turns 20 rpm ccw |
68 | 5 | J. Simmons | ## Verify cadence |
69 | 5 | J. Simmons | ### it should report 30 +/- 10% when wheel turns cw at 30 rpm |
70 | 5 | J. Simmons | ### it should report 45 +/- 15% when wheel turns cw at 45 |
