Operating Instructions

Button Functions:

• ON/OFF Button:
  • Short press: Turns the device ON/OFF.
  • Long press: Activates/Deactivates Bluetooth function.
• MODE/CAL Button:
  • Short press: Cycles through measurement modes (EC/PPM/CL/pH/ORP).
  • Long press: Initiates calibration for EC/SALT/pH/ORP.
• HOLD/TEMP Button:
  • Short press: Locks the current measurement value on the display.
  • Long press: Switches temperature units between Celsius (°C) and Fahrenheit (°F).

Taking Measurements:

1. Turn on the device by short pressing the ON/OFF button.
2. Place the floating unit into the water you wish to test. Ensure the probe is fully immersed.
3. The device will automatically begin measuring. Readings will be displayed on the LCD screen and transmitted to the connected mobile app.
4. Short press the MODE/CAL button to switch between different measurement parameters (pH, EC, ORP, Chlorine, Salinity, Temperature).
5. To hold a reading on the display, short press the HOLD/TEMP button. Press again to release.

Using the Mobile Application:

• Backlight Control: Adjust the display backlight brightness directly from the app.
• Temperature Compensation: Adjust EC temperature compensation settings (default 2.0%/°C).

Calibration

Regular calibration ensures the accuracy of your water quality monitor. Calibration is typically performed for pH, EC, and ORP. Refer to the specific instructions provided with your calibration solutions.

1. Prepare the necessary calibration buffer solutions (e.g., pH 4.00, pH 6.86, pH 9.18 for pH; specific EC/TDS solutions; ORP solution).
2. Turn on the device.
3. Long press the MODE/CAL button to enter calibration mode. The display will indicate the parameter being calibrated.
4. Immerse the probe into the first calibration solution. Wait for the reading to stabilize.
5. Follow the on-screen prompts or app instructions to confirm the calibration point.
6. Rinse the probe with distilled water and dry it gently before proceeding to the next calibration solution.
7. Repeat the process for all required calibration points for the selected parameter.
8. Exit calibration mode once complete.

Note: For detailed calibration steps, especially for EC and ORP, consult the specific instructions within the mobile application or the included quick start guide.

Maintenance

• Cleaning the Probe: After each use, rinse the probe thoroughly with distilled or deionized water to remove any residue. Do not use abrasive materials or harsh chemicals.
• Storage: When not in use, store the device in a cool, dry place. Ensure the probe is kept moist with a storage solution (if applicable for pH electrodes) or in its protective cap.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display or in the app. Ensure the battery compartment is sealed properly after replacement.
• General Care: Wipe the device body with a soft, damp cloth. Do not immerse the entire device in water beyond the probe's intended immersion depth.
