Calibration ensures accurate water measurements and should be done carefully.
🔁 When should I calibrate?
Calibration is recommended:
- Once per season
- After replacing the probe
- If readings seem incorrect or unstable
Calibration is not required for first installation.
⚠️ Before you start
- Do not calibrate while charging the device.
- Keep your phone close to the device with Bluetooth enabled.
- Always use new calibration solutions (single use only).
✅ Calibration order (very important)
- pH calibration
- ORP calibration
Always calibrate pH first, otherwise ORP results may be incorrect.
⏱️ Waiting times
- pH solution: wait 2 minutes before measuring
- ORP solution: wait 20 minutes before measuring
After calibration:
- pH values stabilize after ~3 hours
- ORP values may need up to 6 hours to stabilize
✅ After calibration
Temporary unstable readings are normal. Do not recalibrate again immediately — let the device stabilize in pool water.
