Setup Instructions
Follow these steps for initial setup of your water quality tester.
1. Probe Installation
Image Description: 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.
- Plug the power adapter into the main unit and then into a standard electrical outlet.
- Turn on the device using the ON/OFF switch.
2. Initial Preparation
- 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.
Operating Instructions
This section details how to take measurements and switch between different display modes.
1. Taking Measurements
- 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
Image Description: 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.
- Press the 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. Switching Temperature Units (°C/°F)
Image Description: 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.
- Press the °C/°F key located below the temperature display.
- Each press will toggle the temperature display between Celsius (°C) and Fahrenheit (°F).
Calibration
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. pH Calibration
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).
- Rinse the pH electrode with distilled water and blot dry.
- Immerse the pH electrode into the pH 6.86 buffer solution.
- 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.
- Rinse the electrode again with distilled water.
- 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.
- Press the 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.
Maintenance
Proper maintenance extends the life and accuracy of your water quality tester.
- Electrode Cleaning: After each use, rinse both electrodes thoroughly with distilled or deionized water to prevent contamination and buildup.
- Storage: 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.
- Probe Care: Handle probes gently. Avoid dropping or subjecting them to physical shock.
- Main Unit: Keep the main unit clean and dry. Avoid exposure to direct sunlight, extreme temperatures, or corrosive environments.
- Power: Disconnect the power adapter when the device is not in continuous use for extended periods.
Troubleshooting
If you encounter issues with your device, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device not turning on | No power, faulty adapter, loose connection. | Check power adapter connection. Ensure outlet is functional. Try a different power source if available. |
| Inaccurate pH readings | Electrode not calibrated, dirty electrode, electrode dry, expired buffer solution. | Calibrate pH electrode. Clean electrode with distilled water. Ensure pH electrode is stored in solution. Use fresh buffer solutions. |
| Inaccurate EC/CF/TDS readings | Probe not calibrated, dirty probe, air bubbles on probe. | Calibrate EC/CF/TDS probe. Clean probe. Gently shake probe to dislodge air bubbles. |
| Slow response time | Dirty electrodes, aged electrodes. | Clean electrodes thoroughly. If problem persists, electrodes may need replacement. |
| Fluctuating readings | Unstable sample temperature, air bubbles, electrical interference. | Ensure sample temperature is stable. Remove air bubbles. Move device away from strong electrical fields. |
