• pH Electrode: Measures the acidity or alkalinity of the water.
• EC Electrode: Measures electrical conductivity, which is used to determine EC, CF, and TDS levels. This electrode also integrates the temperature sensor.

4. Setup

Follow these steps to set up your water quality meter:

1. Connect Electrodes: Carefully connect the pH electrode to the BNC connector labeled 'pH' and the EC/Temperature electrode to the BNC connector labeled 'EC/CF/TDS/Temp'. Ensure connections are secure.
2. Power Connection: Plug the provided power adapter into the power supply socket on the side of the main unit, then connect it to a suitable power outlet. The device is designed for continuous operation with the power adapter and includes a rechargeable battery for backup.
3. Mounting (Optional): Use the metal hanging bracket or the plastic mounting brackets to secure the meter to a desired location.
4. Initial Power On: Flip the ON/OFF switch to the 'ON' position. The display should illuminate.

5. Calibration

Accurate calibration is essential for reliable measurements. Calibrate the meter regularly, especially before critical measurements or if readings appear inconsistent.

5.1 Preparing Calibration Solutions

Figure 5: pH buffer powder preparation guidelines.

• pH Buffer Powders: Each packet is designed to make 250ml of calibration solution. Dissolve the contents of one packet into 250ml of distilled water. Stir until fully dissolved. Prepare fresh solutions as needed.
• EC Calibration Solutions: The provided EC 12.88 and EC 1413 solutions are ready to use.

5.2 pH Calibration

1. Ensure the meter is powered on.
2. Rinse the pH electrode with distilled water and gently blot dry.
3. Immerse the pH electrode into the pH 6.86 buffer solution.
4. Wait for the reading to stabilize.
5. Using the mini screwdriver, carefully adjust the 'pH7' calibration knob until the pH display reads 6.86.
6. Rinse the pH electrode again with distilled water.
7. For two-point calibration, immerse the pH electrode into either pH 4.01 or pH 9.18 buffer solution (depending on your expected measurement range).
8. Wait for the reading to stabilize. If necessary, fine-tune the reading using the 'pH7' calibration knob, though typically only one point is adjusted directly. The meter's internal circuitry handles the slope adjustment.

5.3 EC/CF/TDS Calibration

Figure 6: Using the mini screwdriver for calibration adjustments.

1. Ensure the meter is powered on.
2. Rinse the EC electrode with distilled water and gently blot dry.
3. Immerse the EC electrode into the EC 12.88 solution.
4. Press the 'MODE' button to select the EC display.
5. Wait for the reading to stabilize.
6. Using the mini screwdriver, carefully adjust the 'CAL' knob until the EC display reads 12.88.
7. Rinse the EC electrode with distilled water.
8. Repeat the process with EC 1413 solution if a different calibration point is required for your application.

6. Operating Instructions

After proper setup and calibration, the meter is ready for use.

1. Power On: Ensure the meter is switched on.
2. Immerse Electrodes: Submerge both the pH and EC electrodes into the water sample you wish to test. Ensure the electrode tips are fully immersed and there are no air bubbles around them.
3. Read Measurements: Allow a few moments for the readings on the display to stabilize. The meter will simultaneously show pH, Temperature, and the selected EC/CF/TDS value.
4. Change Temperature Unit: Press the '°C / °F' button to switch between Celsius and Fahrenheit temperature displays.
5. Change Conductivity Unit: Press the 'MODE' button to cycle through EC, CF, and TDS readings.
6. Continuous Monitoring: For continuous monitoring, leave the electrodes submerged and the unit powered on. Periodically check readings and recalibrate as needed.
7. Power Off: When finished, switch the meter off and follow maintenance procedures.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your meter.

• Electrode Cleaning: After each use, rinse both electrodes thoroughly with distilled or deionized water to remove any residue. Do not wipe the pH electrode bulb, as this can damage it.
• Electrode Storage: Always keep the protective caps on the electrodes when not in use. The pH electrode tip should ideally be kept moist in a storage solution (e.g., KCL solution or pH 4.0 buffer solution). Do not store the pH electrode dry.
• Unit Cleaning: Wipe the main unit with a clean, damp cloth. Do not use abrasive cleaners or immerse the main unit in water.
• Calibration Solutions: Store calibration solutions in a cool, dark place. Replace them regularly, as they can degrade over time.
• Battery: The meter has a rechargeable battery. Ensure it is charged periodically, especially if the unit will be stored for an extended period without being connected to power.
