4. Produktüberschreitungview

The MOTOCOCHE Digital HVAC Gauges feature a robust design with intuitive controls and a clear digital display for accurate readings.

The gauge provides a dual display interface for simultaneous high and low pressure readings, crucial for comprehensive system diagnostics.

5. Einrichtung und erste Vorbereitung

Before operating the digital gauges, ensure proper connection of the reinforced hoses.

1. Schläuche prüfen: Check the three 5-foot reinforced Freon hoses for any signs of damage or wear. These hoses are designed to withstand pressures up to 600 psi (working) and 3,000 psi (burst).
2. Schläuche anschließen: Attach the appropriate 1/4" male fittings of the hoses to the corresponding ports on the digital manifold gauge. Ensure connections are secure and hand-tightened to prevent leaks. The hose ports are equipped with non-slip gaskets to reduce leakage risk.
3. Einschalten: Press the power button on the digital manifold gauge to turn it on. The display will illuminate.

6. Bedienungsanleitung

The MOTOCOCHE Digital HVAC Gauges offer three primary working modes for various diagnostic tasks:

6.1. Refrigerant Pressure Mode

This mode is used for measuring the pressure of refrigerants within the system. The gauge has a built-in database of 90 refrigerants (e.g., R11, R134A, R410A) and their corresponding temperature sheet data, compliant with US NIST standards. The real-time pressure detection allows for obtaining the corresponding saturation temperature value, which is convenient for calculating subcooling/superheating.

6.2. Vacuum Percentage-Modus

This mode displays the current vacuum pressure and the percentage of the vacuum level. When setting the ultimate vacuum, press the "—" key to reset zero. After vacuumizing, the LCD will display percentages like "97%", "98%" after 3-5 minutes, indicating the vacuum degree. A higher percentage signifies a higher vacuum degree.

6.3. Leak Detection Mode

Utilize this mode to identify potential refrigerant leaks within the system. Follow standard leak detection procedures in conjunction with the gauge's readings.

6.4. Full-Featured Functions

• Automatische Abschaltung: The device is equipped with an automatic power-off function to conserve battery life.
• Einheitenumrechnung: Easily switch between multiple pressure units (KPa, Bar, PSI, InHg, Kgf/cm) and temperature units (°C, °F).
• Hintergrundbeleuchtungsfunktion: The display features a backlight for improved visibility in various lighting conditions.

7. Wartung und Pflege

Proper maintenance ensures the longevity and accuracy of your digital HVAC gauges.

• Reinigung: Reinigen Sie das Gerät mit einem weichen, trockenen Tuch. Verwenden Sie keine Scheuermittel oder Lösungsmittel.
• Lagerung: Store the gauges in a clean, dry place away from direct sunlight and extreme temperatures.
• Batteriewechsel: When the battery indicator shows low power, replace the batteries promptly to ensure accurate readings. Refer to the battery compartment for specific battery type.
• Schlauchinspektion: Regularly inspect the hoses for cracks, kinks, or damage. Replace them if any wear is detected.
