3. Instruccions de funcionament

3.1 Encès/Apagat

Premeu el botó PODER button to turn the meter on. The large LCD will display the current parameter, time, date, and temperature. Press the PODER button again to turn the meter off.

3.2 Selecció de paràmetres

Utilitza el MODE button to cycle through the available measurement parameters: pH, ORP, mV, Conductivity, TDS, Salinity, and Temperature.

3.3 Calibració

The meter features automatic buffer recognition for pH calibration and supports 5 calibration points. Refer to the detailed calibration procedure in the full instruction manual for each specific parameter (pH, ORP, Conductivity, TDS, Salinity).

• Calibració del pH: Use standard pH buffer solutions. The meter will automatically recognize the buffer values.
• Conductivity/TDS/Salinity Calibration: Use appropriate standard solutions.

3.4 Prendre mesures

1. Ensure the appropriate electrode is connected and properly conditioned.
2. Seleccioneu el paràmetre de mesura desitjat mitjançant el botó MODE botó.
3. Immerse the electrode(s) into the sample solution. Ensure the sensor part of the electrode is fully submerged.
4. Allow the reading to stabilize. The meter provides automatic or manual temperature compensation and ranging.
5. The LCD will display the stable measurement.
6. Utilitza el HOLD/REC button to hold the current reading or record data (if connected to PC with software).

4. Manteniment

4.1 Cura dels elèctrodes

• Elèctrode de pH: Always keep the pH electrode bulb moist. Store it in a suitable storage solution or pH 4 buffer when not in use. Never store in distilled water.
• Conductivity Electrode: Rinse the conductivity electrode with distilled water after each use. Store dry or in a conductivity storage solution as recommended.
• Neteja: Clean electrodes regularly according to the full manual's instructions to prevent buildup that can affect accuracy.

4.2 Meter Cleaning

Wipe the meter's housing with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the meter's ports or openings.

4.3 Emmagatzematge

When not in use for extended periods, disconnect the AC adaptor and store the meter and electrodes in a clean, dry environment within the specified operating temperature range.

5. Solució De Problemes

This section addresses common issues you might encounter with your Sper Scientific Benchtop Water Quality Meter 860033.

• Lectures inestables: If readings are unstable, ensure electrodes are properly conditioned and calibrated. Gently stir the sample solution around the probe to help readings settle. Check for air bubbles on the electrode surface.
• Lectures inexactes: Recalibrate the meter with fresh standard solutions. Check electrodes for damage or contamination. Ensure temperature compensation is correctly applied.
• Meter Not Powering On: Verify the AC adaptor is securely connected to both the meter and a working power outlet.
• No Communication with PC: Ensure the computer cable is correctly connected and the software drivers are installed. Check the RS232 port settings on your computer.

For more detailed troubleshooting steps, please refer to the comprehensive instruction manual provided with your device or contact Sper Scientific customer support.
