5. Setup
5.1. Installazzjoni tal-batterija
- Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-miter.
- Use a coin or screwdriver to open the cover.
- Daħħal żewġ (2) batteriji AA, waqt li tiżgura l-polarità korretta (+/-).
- Agħlaq l-għatu tal-kompartiment tal-batterija sew biex iżżomm is-siġill li ma jgħaddix ilma minnu.
The meter is designed for over 500 hours of continuous operation on a fresh set of batteries.
5.2. Konnessjoni tas-Sensor
- Align the connector of the EC sensor (9383-10D) with the sensor input port on the top right side of the meter.
- 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. Istruzzjonijiet Operattivi
6.1. Power On/Off
Agħfas il- Qawwa button (bottom right) to turn the meter on or off.
6.2. Kalibrazzjoni
Regular calibration ensures accurate measurements. The EC220-K supports automatic and manual calibration for EC, TDS, and Salinity.
- Agħfas il- CAL buttuna biex tidħol fil-modalità tal-kalibrazzjoni.
- 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 buttuna.
6.3. Kejl
After calibration, the meter is ready for measurement.
