Precautions for Measurement

When using this module in practice, some people may find it easy to measure successfully, while others may experience frequent measurement failures.
Based on our testing experience, successful measurements rely on several key points.

  1. Place your finger flatly on the measurement area. Your finger should cover the entire measurement area to avoid any interference from indoor lighting.
  2. Do not apply excessive pressure when pressing your finger; keep it relaxed.
  3. Keep the measurement area clean by wiping it with a clean tissue.
★ The measurement needs to take approximately 15 seconds to output the measurement result.
Please keep finger on the measurement area and avoid moving it.
