Instructions d'installation
Follow these steps for initial setup of your water quality tester.
1. Installation de la sonde

Description de l'image : This image displays a four-step visual guide for installing the probes. Step 1 shows the main unit. Step 2 shows connecting the pH electrode to its BNC connector. Step 3 shows connecting the EC/CF/TDS/Temp probe to its input terminal. Step 4 shows both probes fully connected to the main unit, ready for use.
- Unpack all components: main unit, pH electrode, EC/CF/TDS/Temperature probe, and power adapter.
- Connect the pH electrode to the BNC connector on the main unit. Ensure a secure connection.
- Connect the EC/CF/TDS/Temperature probe to its designated input terminal on the main unit.
- Branchez l'adaptateur secteur à l'unité principale, puis à une prise électrique standard.
- Allumez l'appareil à l'aide de l'interrupteur marche/arrêt.
2. Préparation initiale
- Before first use, remove the protective caps from both electrodes.
- Rinse the electrodes with distilled or deionized water.
- Ensure the electrodes are clean and free from any residue.
Mode d'emploi
This section details how to take measurements and switch between different display modes.
1. Prendre des mesures
- Ensure the device is powered on and probes are connected.
- Immerse both the pH electrode and the EC/CF/TDS/Temperature probe into the water sample you wish to test. Ensure the electrodes are fully submerged but do not immerse the entire probe body or cable connections.
- Allow a few moments for the readings to stabilize on the display screens.
- Read the pH, Temperature, and EC/CF/TDS values directly from the respective LCD screens.
2. Switching EC/CF/TDS Modes

Description de l'image : This image illustrates the process of switching between EC, CF, and TDS measurement modes. It shows the main unit with a finger pressing the 'MODE' key. The display cycles through EC (e.g., 1.58), CF (e.g., 0.00), and TDS (e.g., 1000) readings, indicating that pressing the 'MODE' button changes the displayed parameter in the rightmost screen.
- Appuyez sur le MODE key located on the right side of the main unit.
- Each press will cycle the rightmost display between EC (Electrical Conductivity), CF (Conductivity Factor), and TDS (Total Dissolved Solids) readings.
3. Changement d'unité de température (°C/°F)

Description de l'image : This image demonstrates how to change the temperature unit. It shows the main unit with a finger pressing the '°C/°F' key. The temperature display changes from Celsius (e.g., 30.6°C) to Fahrenheit (e.g., 83.0°F), indicating the unit conversion.
- Appuyez sur le ° C / ° F key located below the temperature display.
- Each press will toggle the temperature display between Celsius (°C) and Fahrenheit (°F).
Étalonnage
Regular calibration ensures the accuracy of your water quality tester. It is recommended to calibrate the device upon first use and periodically thereafter, or if readings appear inconsistent.
1. Étalonnage du pH
The pH meter typically requires a two-point or three-point calibration using standard buffer solutions (e.g., pH 6.86, pH 4.01, pH 9.18).
- Prepare the pH buffer solutions (e.g., pH 6.86 and pH 4.01 or pH 9.18).
- Rincez l'électrode de pH à l'eau distillée et séchez-la en la tamponnant.
- Immerger l'électrode de pH dans la solution tampon de pH 6.86.
- Locate the pH7 calibrate adjustment knob on the main unit. Use a small screwdriver to carefully turn the knob until the pH display reads 6.86.
- Rincez à nouveau l'électrode à l'eau distillée.
- Immerse the pH electrode into the second buffer solution (e.g., pH 4.01).
- Adjust the pH4.01/pH9.18 calibration screw (if available, or follow specific instructions for your model's second point calibration) until the display matches the buffer solution value. Note: Some models may have a single pH calibration knob for pH7 and then rely on internal circuitry for the second point. Refer to specific product documentation if available.
- Rinse the electrode and it is now calibrated.
2. EC/CF/TDS Calibration
EC/CF/TDS calibration typically uses a standard conductivity solution (e.g., 1413 µS/cm).
- Prepare a standard EC calibration solution (e.g., 1413 µS/cm).
- Rinse the EC/CF/TDS/Temperature probe with distilled water and blot dry.
- Immerse the EC/CF/TDS/Temperature probe into the calibration solution.
- Appuyez sur le CAL button (if present) or locate the EC/CF/TDS calibration adjustment screw.
- Adjust the calibration screw until the display matches the value of the calibration solution.
- Rinse the probe and it is now calibrated.
Important: Always use fresh calibration solutions. Do not reuse solutions as their values can change over time due to contamination or evaporation.
Entretien
Proper maintenance extends the life and accuracy of your water quality tester.
- Nettoyage des électrodes: After each use, rinse both electrodes thoroughly with distilled or deionized water to prevent contamination and buildup.
- Stockage: Always replace the protective caps on the electrodes when not in use. The pH electrode cap should contain a small amount of storage solution (or pH 4 buffer) to keep the glass bulb hydrated. Do not store pH electrodes dry.
- Entretien de la sonde : Handle probes gently. Avoid dropping or subjecting them to physical shock.
- Unité principale : Keep the main unit clean and dry. Avoid exposure to direct sunlight, extreme temperatures, or corrosive environments.
- Pouvoir: Disconnect the power adapter when the device is not in continuous use for extended periods.
