Magnetometer Troubleshooting
Magnetometer Part is U6140.
•
If no reading:
•
– Verify U6140 orientation
Verify voltage at C6141 is 1.8V
–
– Replace U6140, if still not fixed try replacing U6150, then possibly
U6000
If reading is failing:
•
Replace U6140, likely damaged magnetometer part.
–
– Test at board level if radio level testing is failing to determine if
magnetic component in the housing is somehow affecting readings.
