6. Betjeningsvejledning
6.1. Tænd/sluk
Tryk på Magt button (bottom right) to turn the meter on or off.
6.2. Kalibrering
Regular calibration ensures accurate measurements. The EC220-K supports automatic and manual calibration for EC, TDS, and Salinity.
- Tryk på CAL knappen for at gå ind i kalibreringstilstand.
- 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 SÆT button and arrow keys.
- Confirm calibration with the ØNH knap.
6.3. Måling
After calibration, the meter is ready for measurement.
