6. Setup
Follow these steps for initial setup of your Camnoon Electronic Refrigerant Fluoride Meter:
- Battery Installation: Open the battery compartment on the back of the unit. Insert 3 AA batteries, ensuring correct polarity. Close the compartment securely.
- Hose Connection: Connect the appropriate refrigerant hoses (if included in your set) to the LOW, HIGH, and SERVICE ports on the manifold gauge. Ensure all connections are tight to prevent leaks.
- System Connection: Connect the hoses to the refrigeration or air conditioning system's low-pressure, high-pressure, and service ports as required for your specific task (e.g., charging, evacuation, pressure testing).
7. Operating Instructions
This section outlines general operating procedures. Refer to specific HVAC/R service guidelines for detailed application steps.
- Power On: Press the power button to turn on the device. The LCD display will illuminate.
- Refrigerant Selection: Use the 'FN' button to cycle through the built-in refrigerant types until the desired refrigerant (e.g., R134A) is displayed.
- Unit Selection: Press the 'UNIT' button to select the preferred pressure and temperature units (e.g., Kpa, PSI, °C, °F).
- Zeroing: Before taking measurements, ensure the system is isolated and press the 'ZERO' button to calibrate the pressure sensors to zero.
- Pressure Measurement: Open the appropriate valves on the manifold to measure the high-side (HP) and low-side (LP) pressures of the system. The values will be displayed in real-time.
- Vacuum Measurement: For evacuation, connect the vacuum pump to the service port. The meter will display the vacuum degree in real-time.
- Temperature Display: The device will calculate and display evaporation and condensation temperatures based on the selected refrigerant and measured pressures.
- Leakage Test: The meter can record leakage time and speed. Consult the on-screen prompts or a more detailed guide for specific leakage test procedures.
- Power Off: Press and hold the power button to turn off the device after use.
