6. Kalibrering
Regular calibration is essential for accurate measurements. The LAQUA EC210-K supports both automatic and manual calibration procedures.
6.1. EC Calibration
- Tryk på CAL knappen for at gå ind i kalibreringstilstand.
- Follow the on-screen prompts to select automatic or manual calibration.
- For automatic calibration, immerse the sensor in the appropriate standard solution. The meter will automatically recognize the solution and calibrate.
- For manual calibration, immerse the sensor in a standard solution and use the arrow buttons to adjust the reading to match the known value. Press ØNH for at bekræfte.
- The meter allows adjustment of reference temperature, temperature coefficient, and cell constant for precise measurements.
6.2. TDS and Salinity Calibration
- The meter provides EC to TDS conversion with four selectable TDS calibration curves.
- Two salinity calibration curves are available for accurate salinity measurements.
- Der henvises til SÆT menu for selecting and configuring these curves.
7. Datastyring
The LAQUA EC210-K includes features for efficient data handling:
- Auto Log Data: Automatically records measurement data at set intervals.
- Indbygget hukommelse: Stores up to 500 data points, allowing for comprehensive record-keeping.
- Auto Stable/Auto Hold: Ensures stable readings are captured and held on the display.
- Real-time Measurement: Provides continuous display of current readings.
To access stored data, press the DATA button and navigate using the arrow keys.
8. Vedligeholdelse
