5.1. ເປີດ/ປິດ
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. ການວັດແທກ
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.

5.4. ການຕັດໄມ້ຂໍ້ມູນ
The SM480V can log data internally. To initiate data logging:
- Navigate to the data logging menu.
- Set the desired logging duration and interval.
- Start the logging process. The manifold will store measurements, which can be downloaded later via the Micro USB port.
5.5. System Tightness Test
Utilize the temperature compensated system tightness test feature to accurately detect leaks in the system. Follow the on-screen prompts to perform the test.
5.6. Wireless Connectivity (Job Link App)
Connect your SM480V to the Fieldpiece Job Link app on your smartphone or tablet for remote monitoring, advanced diagnostics, and report generation. This allows you to view readings from a distance and manage job data efficiently.
