6.5.3 Device Usage

The basic usage model of the FDC1004-Q1 is to simply follow these steps:

  1. Configure measurements (for details, refer to Measurement Configuration).
  2. Trigger a measurement set (for details, refer to Triggering Measurements).
  3. Wait for measurement completion (for details, refer to Wait for Measurement Completion).
  4. Read measurement data (for details, refer to Read of Measurement Result).
