3. Setup
3.1 Battery Installation
- Unscrew the top cap of the meter to access the battery compartment.
- Insert three LR44 button cells, ensuring correct polarity.
- Securely replace the top cap.
3.2 Calibration (pH)
Regular calibration ensures the accuracy of your pH readings. It is recommended to calibrate the pH function before first use and periodically thereafter.
- Prepare pH buffer solutions: Dissolve the provided pH buffer powders (e.g., pH 6.86, pH 4.00, pH 9.18) in 250ml of distilled water each.
- Turn on the meter by pressing the ON/OFF button.
- Immerse the electrode into the pH 6.86 buffer solution.
- Press and hold the "MODE/CAL" button for 5 seconds until the display shows "CAL".
- The meter will automatically recognize the buffer solution and calibrate. Wait for the reading to stabilize and display "END" before removing.
- Rinse the electrode with distilled water.
- Repeat steps 3-6 for pH 4.00 and pH 9.18 buffer solutions if a multi-point calibration is desired for higher accuracy.
Note: Salinity, TDS, and EC functions are typically factory calibrated and do not require user calibration.

4. Operating Instructions
4.1 General Measurement Procedure
- Power On: Press the ON/OFF button to turn on the meter.
- Select Mode: Press the "MODE/CAL" button repeatedly to cycle through the measurement modes (Salinity, pH, TDS, EC, Temperature) until the desired mode is displayed.
- Immerse: Remove the protective cover. Immerse the electrode part of the meter into the water sample, ensuring it does not exceed the maximum immersion line. Stir gently for a few seconds to remove air bubbles and ensure a stable reading.
- Read Value: Wait for the reading to stabilize on the LCD screen.
- Hold Reading: To lock the current reading, press the "HOLD/TEMP" button. Press it again to release.
- Power Off: After use, rinse the electrode with distilled water, replace the protective cover, and press the ON/OFF button to turn off the meter.
A visual guide demonstrating the simple three-step operation of the Pawfly 5-in-1 Water Quality Tester: pressing the power button, immersing the probes in water and stirring, and using the HOLD/TEMP button to lock the readings. A note advises against immersing the device beyond the maximum immersion line.
4.2 Temperature Unit Switching
While in any measurement mode, press and hold the "HOLD/TEMP" button for 3 seconds to switch the temperature unit between Celsius (°C) and Fahrenheit (°F).
4.3 Interpreting Salinity Readings for Pools
For swimming pools, maintaining the correct salinity level is crucial for effective disinfection and equipment longevity. Refer to the following guidelines:

4.4 Interpreting pH Readings for Pools
Maintaining an ideal pH range in pools is essential for swimmer comfort and sanitizer efficiency.

5. Maintenance
- Cleaning the Electrode: After each use, rinse the electrode thoroughly with distilled or deionized water to prevent contamination and residue buildup. Do not use tap water for rinsing if possible, as it may contain minerals that affect sensor performance.
- Storage: Always replace the protective cap after use. For long-term storage, ensure the electrode is kept moist. If the electrode dries out, soak it in electrode storage solution or pH 4.0 buffer solution for several hours before use.
- Battery Replacement: When the display becomes dim or the meter fails to power on, replace the LR44 button cells.
- Avoid Immersion Beyond Max Line: Never immerse the meter beyond the maximum immersion line indicated on the device to prevent damage to internal electronics.
- Handle with Care: The glass pH sensor is delicate. Avoid dropping the meter or subjecting it to harsh impacts.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate pH readings | Meter not calibrated; electrode dirty or dry. | Calibrate the pH function using buffer solutions. Clean the electrode and ensure it is kept moist. |
| Unstable readings | Air bubbles around electrode; insufficient immersion; electrode damage. | Stir gently to remove air bubbles. Ensure electrode is fully immersed below the max line. Inspect electrode for damage. |
| Meter does not power on | Dead batteries; incorrect battery installation. | Replace batteries with new LR44 cells. Check battery polarity. |
| Display is dim | Low battery power. | Replace batteries. |
| Water inside the unit | Immersion beyond max line; loose cap. | Ensure the meter is not immersed past the max line. Tighten the battery cap securely. If water ingress occurs, discontinue use and contact support. |
