3. Placing the Probes: Submerge the pH, ORP, and temperature probes into the water body you wish to monitor (e.g., aquarium, hydroponic system). Ensure the probes are fully immersed and securely positioned.

   This image shows the GAIN EXPRESS controller connected and installed in an aquarium, with the pH, ORP, and temperature probes submerged in the water.
4. Connexió d'alimentació: Connect the power supply to the controller unit and then plug it into a standard AC outlet (AC120V or AC220V, depending on your region). The LCD screen will illuminate.
5. Connexió Wi-Fi: Ensure your Wi-Fi network is 2.4 GHz for compatibility with the device and its mobile application. Refer to the separate Wi-Fi setup guide for detailed instructions on connecting the controller to your network and mobile app.

5. Funcionament bàsic

Once the controller is powered on and probes are submerged, it will begin displaying real-time pH, ORP, and temperature readings on its LCD screen.

• Visualització en temps real: The LCD shows current pH, ORP, and temperature values.
• Control de la llum de fons: The controller features backlight control for improved visibility in various lighting conditions.
• Compensació de temperatura: The device automatically compensates for temperature variations in measurements within the range of 0~50°C.

6. Calibració

Regular calibration ensures the accuracy of your pH and ORP readings. The pH electrode requires 3-point calibration.

1. Calibració del pH:
   • Prepare the pH buffer solutions (pH 4.0, pH 6.86, pH 9.18) using the provided powders and distilled water.
   • Press the "CAL" button next to the pH/TEMP display on the controller.
