5. Operating Instructions

5.1. Power On/Off

Press and hold the power button to turn the unit on or off. A short press will toggle the backlight.

5.2. Selecting Refrigerant

Use the 'MENU' button to navigate to the refrigerant selection. Use the arrow buttons to scroll through the available refrigerants (e.g., R22, R410A, R134a, R404A, R407C, R448A, R449A, R452A, R32, R454B, R454C, R407A, R407F, R422B, R422C, R422D, R507A, R513A, R1234yf, R1234ze, R600a, R290, R744). Press 'ENTER' to confirm your selection. The SM480V supports downloading new refrigerants via the Job Link app.

5.3. Taking Measurements

Once connected to the system and refrigerant is selected, the manifold will display real-time pressure and temperature readings. Superheat and subcooling values will be calculated automatically based on the connected thermocouples.
