2. Informazzjoni dwar is-Sigurtà

Dejjem osserva l-prekawzjonijiet ta' sigurtà li ġejjin biex tevita korrimenti jew ħsara lit-tagħmir:

• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling refrigerants.
• Aċċerta ruħek li jkun hemm ventilazzjoni xierqa meta taħdem bir-refriġeranti.
• Do not exceed the maximum operating pressure of the hoses (600 PSI / 4.13 MPa). The limit pressure is 3000 PSI.
• Verify that all connections are secure before applying pressure.
• Avoid direct contact with refrigerants, as they can cause frostbite.
• Żomm l-apparat 'il bogħod mill-ilma u temperaturi estremi.
• Ensure the temperature sensor clips are properly connected for accurate readings.

3. Karatteristiċi tal-prodott

The CMTOOL Digital HVAC Manifold Gauge Set offers several advanced features for HVAC professionals:

• Dual Pressure and Dual Temperature Measurement: Simultaneously measures two pressures (gauge pressure) and two temperatures.
• Automatic Unit Conversion: Supports automatic conversion for pressure (kPa, MPa, Psi, Bar, InHg) and temperature (Celsius/Fahrenheit).
• High-Precision Data Unit: Features a built-in 32-bit digital processing unit and high-precision data acquisition for stable and accurate readings.
• Refrigerant Database: Contains a built-in database of 89 refrigerants, allowing for direct reading of pressure-evaporation temperature, superheat, and subcooling.
• Vacuum Measurement: Tests the percentage of vacuum.
• Test tan-nixxija tal-pressjoni: Calculates pressure difference over time to detect refrigerant leaks.
• Kostruzzjoni Durabbli: Made with high-strength engineering plastics and flexible non-slip silicone for durability and comfortable handling.
• Viewable Window and LCD Display: Allows direct observation of refrigerant charging status and features a 7.5CM×4CM LCD with backlight for clear data reading.

5.1 Mixgħul/Mitfi u Dawl ta' Wara

• Press the Power Button (11) to turn the device on or off.
• Press the Backlit Button (9) to activate or deactivate the LCD backlight for improved visibility in low-light conditions.

5.2 Selecting Refrigerant Type

• Use the R+/R- Refrigerant Type Selection Buttons (6) to scroll through the built-in refrigerant database and select the refrigerant being used (e.g., R134A, R410A).

5.3 Kejl tal-Pressjoni u t-Temperatura

The device displays dual pressure and dual temperature readings simultaneously.

• Ensure hoses and temperature clamps huma konnessi b'mod korrett.
• The LCD Display (2) will show T1 and T2 temperatures, along with corresponding pressures.
• Press the Unit Button (7) to cycle through different pressure units (kPa, MPa, Psi, Bar, InHg).
• Press the °C/°F Button (10) to switch between Celsius and Fahrenheit temperature units.
