Calibration Guide
1️⃣ Heart Rate Calibration
✔ Wear the watch snugly, one finger above the wrist bone
✔ Sit still for 1–2 minutes
✔ Keep arm resting on a table
✔ Run 3 heart rate measurements in a row
→ The watch will auto-learn your pulse pattern
2️⃣ Blood Pressure Calibration
Smartwatches estimate BP using optical sensors, so calibration is important.
✔ Sit relaxed for 2–3 minutes
✔ Keep the watch at heart level
✔ Take 3 readings, 30 seconds apart
✔ Stay still and don’t talk
✔ For best results, calibrate at the same time daily
→ The watch uses your baseline to improve accuracy over time
3️⃣ Blood Oxygen (SpO₂) Calibration
✔ Sit still and rest your hand
✔ Avoid bright sunlight
✔ Run 2–3 measurements
✔ Ensure the back sensor touches the skin fully
→ The watch adjusts to your skin type + circulation
4️⃣ Sleep Tracking Calibration
✔ Wear the watch 1 hour before bed
✔ Allow 3 full nights for the algorithm to learn your patterns
✔ Keep the strap slightly snug
→ Sleep accuracy improves each night
5️⃣ Step Count & Distance Calibration
✔ Walk naturally for 30–60 seconds
✔ Make sure the strap is secure
✔ Allow 24 hours of movement data
→ Steps + distance become more precise as GPS-free systems learn your gait
6️⃣ Glucose Trend (AI Estimation) Calibration
Life Watch Pro uses optical data + HRV + temperature + long-term trends.
✔ Wear the watch for 6–8 hours continuously
✔ Keep the watch snug
✔ Allow 3–5 days for trend learning
→ This does not replace medical glucose meters
General Tips for Best Accuracy
✔ Keep sensors clean
✔ Wear snugly — not loose, not tight
✔ Avoid tattoos or very hairy areas
✔ Avoid moving while measuring
✔ Re-calibrate after firmware updates
✔ Wear it consistently — the watch learns from data
