- Remove the protective cap from the probe before use.
4. Operating Instructions
4.1 Basic Measurement
- Ensure the device is powered on and the protective cap is removed from the probe.
- Immerse the probe into the water sample you wish to test. Ensure the probe is fully submerged.
- Press the 'MODE/CAL' button to select the desired measurement parameter (e.g., pH, FAC, Salt).
- Wait for the reading on the LCD display to stabilize. The reading will show the measured value and temperature.
- For accurate FAC readings, ensure the pool water pH is between 6.5-8 and ORP is between 487-840mV.
4.2 Data Hold Function
- During measurement, a short press of the 'HOLD/TEMP' button will freeze the current reading on the display. An 'H' icon will appear on the screen.
- Press 'HOLD/TEMP' again to release the hold and resume live measurement.
4.3 Temperature Unit Conversion
- To switch the temperature unit between Celsius (°C) and Fahrenheit (°F), long press the 'HOLD/TEMP' button.
5. Calibration
The YAGO YY-1070 is factory-calibrated for all functions. It is recommended to recalibrate the meter every 2-4 weeks to maintain optimal accuracy, or if you suspect inaccurate readings.
5.1 Calibration Solutions
Use standard buffer solutions for calibration:
- pH Calibration: pH 6.86, pH 4.00, pH 9.18
- ORP Calibration: ORP 222mV
5.2 Calibration Procedure
For detailed calibration steps for each parameter (pH, ORP, EC, TDS, Salinity), please refer to the specific instructions provided in the physical instruction manual included with your product. The general process involves:
- Prepare the appropriate calibration solution.
- Immerse the probe into the calibration solution.
- Enter calibration mode by long-pressing the 'MODE/CAL' button (or as specified in the manual).
- Adjust the reading to match the known value of the calibration solution.
- Confirm calibration and exit the mode.

7. Maintenance
- Electrode Cleaning: Always clean the electrodes thoroughly with distilled water after each use to prevent contamination and ensure accurate future readings.
- Storage: Replace the protective cap on the probe when not in use to keep it moist and protected. Store the device in a cool, dry place.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears on the display to ensure continuous operation.
- Probe Replacement: The high-precision probes are removable and replaceable. If a probe becomes damaged or its accuracy degrades significantly, it can be twisted off and a new one installed.
8. Troubleshooting
8.1 FAC Value Displays 0 or '----'
Problem: The Free Available Chlorine (FAC) value is displayed as 0 or '----'.
Solution: For the FAC value to display normally, the swimming pool water's pH should be between 6.5-8 pH, and the ORP should be between 487-840 mV. If either the pH or ORP value is outside this specified range, the FAC reading will not be displayed correctly.
8.2 Discrepancy with Reagent Test Papers
Problem: The device detects 0 residual chlorine, but a reagent test paper shows a different value.
Solution: The detection principles of the YAGO YY-1070 digital tester and traditional test papers are different. Test papers often have a larger margin of error and cannot be accurately compared with the precise readings provided by electronic equipment.
9. User Tips
- Optimal Pool Conditions: For saltwater pools, aim for a salt level between 2700-3400 ppm. Maintain a pH level between 7.2 and 7.8 for comfortable swimming and to protect pool equipment.
- Versatile Applications: This tester is suitable for a wide range of uses, including drinking water, sewage treatment, fish tanks, aquaculture, swimming pools, hydroponics, and medical care.
- TDS Interpretation: Lower TDS values generally indicate purer water quality. Refer to the TDS chart for common water quality classifications.
