5. Informació de seguretat

• Do not immerse the main meter unit in water. Only the probes are designed for submersion.
• Handle electrode probes with care. They are fragile and can be damaged by impact.
• Keep the device and calibration solutions out of reach of children.
• Feu servir només l'adaptador de corrent proporcionat o un de compatible amb el volum correcte.tage i especificacions actuals.
• Avoid exposing the device to direct sunlight for prolonged periods, as this may affect the display.
• Assegureu-vos que hi hagi una ventilació adequada quan feu servir el dispositiu.

6. Configuració

6.1 Desembalatge i inspecció

Carefully remove all components from the packaging. Inspect the meter and probes for any visible damage. If any damage is found, do not proceed with setup and contact customer support.

6.2 Connexió de sondes

1. Connect the pH electrode probe to the BNC connector on the main unit. Ensure it is securely twisted into place.
2. Connect the EC/Temperature electrode probe to the designated port on the main unit.

6.3 Encès

Plug the power adapter into the DC input port on the main unit, then connect the adapter to a suitable power outlet. The LCD display should illuminate, indicating the device is powered on.

6.4 Muntatge del mesurador

The meter can be mounted using the provided mounting bracket and suction cups. Attach the bracket to the back of the meter, then use the suction cups to secure it to a clean, smooth surface, such as the side of an aquarium or reservoir.

7. Funcionament

7.1 Prendre mesures

1. Ensure the meter is powered on and probes are connected.
2. Submerge both the pH electrode and the EC/Temperature electrode into the solution to be tested. Ensure the liquid level covers the sensing elements of both probes.
3. Allow a few moments for the readings to stabilize on the LCD display. The meter will show pH, EC, and temperature simultaneously.

7.2 Unitats de commutació

• Temperature Units (°C/°F): Press the 'TEMP/CAL' button to toggle between Celsius and Fahrenheit temperature displays.
• EC Units (us/cm / ms/cm): Press the 'MODE' button to switch between microsiemens per centimeter (us/cm) and millisiemens per centimeter (ms/cm) for EC readings.

8. Calibració

Regular calibration ensures the accuracy of your meter. Calibration should be performed when the meter is new, after electrode replacement, or if readings appear inaccurate.

8.1 Calibració de pH

The pH chip features an automatic calibration function that can identify standard calibration liquids. For best results, use pH 4.00 and pH 6.86 buffer solutions.

1. Prepare two clean beakers with pH 6.86 and pH 4.00 buffer solutions, respectively.
2. Rinse the pH electrode with distilled water and gently blot dry.
3. Submerge the pH electrode into the pH 6.86 buffer solution.
4. Press and hold the 'TEMP/CAL' button until the display shows 'CAL'. The meter will automatically detect the buffer and calibrate. Wait for the reading to stabilize and the calibration process to complete.
5. Rinse the pH electrode again with distilled water.
6. Submerge the pH electrode into the pH 4.00 buffer solution.
7. Press and hold the 'TEMP/CAL' button again. The meter will automatically calibrate to pH 4.00.
8. After calibration, rinse the electrode and store it properly.

8.2 EC Calibration

EC calibration is performed using a standard EC solution (e.g., 1413 us/cm or 12.88 ms/cm) and the provided mini screwdriver.

1. Prepare a clean beaker with a known EC standard solution.
2. Rinse the EC electrode with distilled water and gently blot dry.
3. Submerge the EC electrode into the standard EC solution.
4. Locate the EC calibration trimmer on the meter (usually a small screw hole).
5. Using the mini screwdriver, carefully turn the trimmer until the EC reading on the display matches the value of your standard solution.
6. Rinse the electrode with distilled water after calibration.

9. Manteniment

9.1 Electrode Cleaning and Storage

• Always rinse the electrodes with distilled or deionized water before and after each use to prevent contamination.
• For long-term storage, the pH electrode should be kept moist. Use a storage solution or pH 4.00 buffer solution in the electrode cap. Do not store in distilled water.
• The EC electrode can be stored dry after rinsing.
• If electrodes become fouled, gently clean them with a soft brush and a mild detergent solution, then rinse thoroughly.

9.2 Substitució d'elèctrodes

The electrode probes are replaceable. If an electrode becomes damaged or consistently provides inaccurate readings even after calibration, it may need to be replaced. Contact your supplier for compatible replacement probes.
