Introduction
The RCYAGO BLE-C600 is a versatile 7-in-1 digital meter designed for comprehensive water quality testing. It accurately measures pH (acidity and alkalinity), EC (conductivity), TDS (total dissolved solids), Salinity (salt content), S.G (Specific Gravity), ORP (Oxidation-Reduction Potential), and temperature. This device features automatic temperature compensation (ATC) and Bluetooth connectivity for seamless data management via a mobile application. It is suitable for various applications.

- High-Precision Probe: Equipped with a sensitive glass probe for accurate measurements.
- Multi-Parameter Display: Large LCD display shows multiple parameters simultaneously.
- Button Battery Power: Uses 3*1.5V button batteries (located under the top cap).
- Backlight Display: App-controlled backlight for improved visibility.
- Data Hold/Temperature Unit Conversion Key ({HOLD/TEMP}): Locks the measured value and switches between Celsius and Fahrenheit.
- Function Conversion/Calibration Key ({MODE/CAL}): Switches between pH, EC, TDS, Salinity, S.G, and ORP measurements, and initiates calibration.
- ON/OFF Key: Powers the device on or off.
- Protective Cap: Covers the electrode for protection when not in use.
- Immersion Line: Indicates the minimum immersion depth for accurate readings.

Setup
1. Battery Installation
- Unscrew the top cap of the meter.
- Insert 3*1.5V button batteries into the battery compartment, ensuring correct polarity.
- Securely screw the top cap back on.
2. Initial Preparation
- Remove the protective cap from the electrode.
- Rinse the electrode with distilled water before first use.
3. Bluetooth Connection and App Setup
The meter connects to your smartphone via Bluetooth for enhanced functionality and data management. Ensure your phone's Bluetooth is enabled.

- Download the official RCYAGO app (refer to product packaging or included QR code for download instructions).
- Press and hold the ON/OFF button on the meter for 5 seconds to turn on or off Bluetooth. The Bluetooth icon will appear on the meter's display.
- Open the app on your smartphone. The app will automatically search for and connect to the meter.
- Once connected, the app will display real-time readings from the meter.
Operating Instructions
1. Taking a Measurement
- Ensure the meter is powered on.
- Immerse the electrode into the solution to be tested, ensuring the immersion line is covered.
- Wait for the readings to stabilize on the LCD display.
- Press the {MODE/CAL} key to cycle through the different measurement parameters: pH, EC (uS/cm), TDS (ppm), Salinity (ppm/%), S.G, and ORP (mV).
- To hold the current reading on the display, press the {HOLD/TEMP} button. Press again to release.
- To switch temperature units (Celsius/Fahrenheit), long-press the {HOLD/TEMP} button.
2. App Functions
The mobile app provides advanced control and data management features:
- Real-time Display: View all 7 parameters simultaneously on your phone screen.
- Backlight Control: Toggle the meter's backlight on/off directly from the app.
- Data Saving: Manually save measurement data to the app's history.
- Data Management: Access saved data, view calibration records, and share test results.
- Parameter Limits: Set upper and lower limits for pH, EC, and ORP. If a measured value exceeds these limits, it will be displayed in red on the app interface, alerting you to abnormal readings.

Calibration
The pH meter features a 5-point calibration method for high accuracy. Calibration powders for Asia Standard (pH 4.00, pH 6.86, pH 9.18) and EU Standard (pH 7.00, pH 10.01) are included. Always clean the electrode with distilled water between different buffer solutions.

pH Calibration Procedure:
- Prepare the buffer solutions (e.g., pH 4.00, pH 6.86, pH 9.18) according to their instructions.
- Turn on the meter and ensure it's connected to the app.
- Immerse the electrode into the first buffer solution (e.g., pH 4.00).
- Press and hold the {MODE/CAL} key for 5 seconds until "CAL" appears on the display and the reading starts flashing.
- Wait for the reading to stabilize and flash 3 times, indicating successful calibration for that point.
- Rinse the electrode thoroughly with distilled water.
- Repeat steps 3-5 for the remaining buffer solutions (e.g., pH 6.86 and pH 9.18).
- Calibration records can be viewed in the app.
