Salinity Meter Calibration Steps
1. Immerse the meter in distilled water and activate it for about a few hours.
2. Immerse the meter in the 35ppt calibration solution (25°C) and gently stir to prevent air bubbles around the electrodes.
3. After the reading is stable, use a small screwdriver to turn the calibration trimmer on top of the salinity meter until the display shows 35ppt.
4. Rinse with distilled water after calibration and use it to measure the target solution.
