Quickstart Guide

Get your Data Walker device ready for clinical use in about 5 minutes.

Prerequisites

  • Assembled Data Walker device with Hall sensor

Step 2: Run the Self-Test

After flashing, the device boots into the self-test screen automatically.

For highest accuracy, calibrate against a known distance:

  1. Mark out a 14-meter course (for 10-meter walk test)
  2. Navigate to Tests → 10-meter walk
  3. Complete 3 test runs
  4. Accept the auto-suggested calibration factor
