- Gently push and twist the connector clockwise until it is securely fastened. Do not overtighten.
- Ensure the sensor is clean and free from air bubbles before use.
6. Instrucțiuni de utilizare
6.1. Pornire/Oprire
Apăsați tasta Putere button (bottom right) to turn the meter on or off.
6.2. Calibrare
Regular calibration ensures accurate measurements. The EC220-K supports automatic and manual calibration for EC, TDS, and Salinity.
- Apăsați tasta CAL buton pentru a intra în modul de calibrare.
- Follow the on-screen prompts to select the appropriate calibration standard solution.
- Immerse the sensor in the standard solution. The meter will detect the solution and perform automatic calibration.
- For manual calibration or adjustment of reference temperature, temperature coefficient, or cell constant, use the SET button and arrow keys.
- Confirm calibration with the ENT buton.
6.3. Măsurare
After calibration, the meter is ready for measurement.
- Apăsați tasta MĂSURI button to enter measurement mode.
- Apăsați tasta MOD button to cycle through measurement parameters: Conductivity (EC), Total Dissolved Solids (TDS), Salinity (SAL), and Resistivity (RES). Temperature is displayed concurrently.
- Cufundați senzorul în sample solution. Ensure the sensor tip is fully submerged and free of air bubbles.
- Wait for the reading to stabilize. The 'Auto Stable' feature will indicate when the reading is stable.
- The meter can display temperature in both Celsius (°C) and Fahrenheit (°F), adjustable in the settings.
