2. Segurtasun informazioa

Beti jarraitu segurtasun neurri hauek ekipamenduari lesioak edo kalteak saihesteko:

• Hozgarriak maneiatzen dituzunean, erabili babes pertsonaleko ekipamendu (EPI) egokia, segurtasun-betaurrekoak eta eskularruak barne.
• Ensure proper ventilation when working with refrigerants.
• 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.
• Mantendu gailua uretatik eta muturreko tenperaturatik urrun.
• Ensure the temperature sensor clips are properly connected for accurate readings.

3. Produktuaren ezaugarriak

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.
• Presio ihesaren proba: Calculates pressure difference over time to detect refrigerant leaks.
• Eraikuntza iraunkorra: 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.

4.2 Connecting Hoses and Clamps

1. Connect the appropriate test hoses to the low pressure inlet (14), high pressure inlet (17), and refrigerant/vacuum pump inlet (18) on the manifold gauge.
2. Attach the other ends of the hoses to the service ports of the HVAC system.
3. Plug the temperature clamps into the Clamp-on Temperature Probe Sockets (1).
4. Securely attach the temperature clamps to the refrigerant pipes to measure pipe surface temperature.

5. Funtzionamendu-argibideak

5.1 Piztea/itzaltzea eta atzeko argia

• 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 Presioaren eta Tenperaturaren Neurketa

The device displays dual pressure and dual temperature readings simultaneously.

• Ensure hoses and temperature clampbehar bezala konektatuta daude.
• 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.

5.5 Presio-ihesaren proba

To perform a pressure leak test:

1. Connect the gauge to the system and pressurize it.
2. Press the Function Button (3) to enter the leak test mode.
3. The gauge will record the initial pressure and continuously monitor for changes.
4. The display will show the leak time (HH:MM) and the pressure difference (ΔP) between the initial and instantaneous pressure values.
