5. Operating Instructions

5.1 Taking a Measurement

1. Prepare Sample: Obtain a sample of the water you wish to test (e.g., tap water, filtered water, bottled water).
2. Immerse Probe: 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.
3. Activate Measurement: Press the measurement button (usually indicated by a power/start icon) to initiate the test.
4. Read Results: 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:

• Blue Backlight: Excellent Water Quality
• Green Backlight: Good Water Quality
• Yellow Backlight: Average Water Quality
• Red Backlight: Poor Water Quality

6. Maintenance

• Probe Cleaning: After each use, rinse the probe thoroughly with clean water to prevent residue buildup. For stubborn deposits, gently wipe with a soft, damp cloth. Do not use abrasive materials or harsh chemicals.
• Storage: Store the LS310 in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the probe is dry before storage.
• Battery Care: If the device uses replaceable batteries, remove them if the device will not be used for an extended period to prevent leakage.

7. Troubleshooting

• Device Not Powering On:
  • Check if batteries are correctly inserted or if the device needs charging.
  • Ensure the power button is pressed firmly.
• Inaccurate Readings:
  • Ensure the probe is clean and free from air bubbles.
  • Verify the water sample is sufficient to cover the probe's sensors.
  • Perform a calibration if available (refer to specific calibration instructions if provided with the device).
• Display Issues:
  • If the screen is dim, check battery levels.
  • If the screen is frozen, try restarting the device.
