4. Guia de configuració
- Desembalatge: Carefully remove the LS310 water quality tester from its packaging.
- Inspecció inicial: Check the device for any visible damage. Ensure the probe area is clean and free from debris.
- Encès: Press the power button to turn on the device. The TFT color screen should illuminate.
5. Instruccions de funcionament
5.1 Prendre una mesura
- Preparar SampLI: Obteniu comample of the water you wish to test (e.g., tap water, filtered water, bottled water).
- Sonda d'immersió: Gently immerse the probe end of the LS310 tester into the water sample. Ensure the water level reaches at least the 'lowest water mark' indicated on the device.
- Activate Measurement: Press the measurement button (usually indicated by a power/start icon) to initiate the test.
- Llegir resultats: The device will display the COD, TOC, UV275, TDS, EC, and temperature readings on the TFT screen. The screen's backlight color will also indicate the overall water quality score.

5.2 Interpreting Water Quality Scores
The LS310 provides an intelligent scoring system with four distinct water quality levels, indicated by the screen's backlight color:
- Retroil·luminació blava: Excellent Water Quality
- Retroiluminació verda: Good Water Quality
- Retroiluminació groga: Average Water Quality
- Retroiluminació vermella: Mala qualitat de l'aigua
