4.2. Pressure Holding Test (Requires In-App Purchase)
This function allows you to test the pressure integrity of your system.
- Connect the high-pressure refrigerant hose to the testing system and close the high-pressure valve.
- In the app, navigate to 'Settings' and then 'Hold Pressure Setting'.
- Set the charging warning value, decay ratio, enable/disable temperature compensation, and set the pressure-holding time.
- On the device, press and hold the 'MODE' and 'Down Arrow' keys simultaneously to enter the pressure-holding test.
- Inject gas into the system until the pressure reaches the charging warning value. The device will flash and emit a sound.
- Click the 'Down Arrow' button on the device to begin the leak test. The timer will start counting down.
- If the pressure remains within the acceptable leak value (calculated based on decay ratio), the test is successful. Otherwise, it indicates a leak.
4.3. Vacuum Measurement (Requires In-App Purchase)
Measure the vacuum level of your system.
- Connect the system to the high-pressure side of the manifold and open the high-pressure valve.
- Simultaneously press the 'MODE' and 'Down Arrow' buttons twice on the device to enter the vacuum mode.
- Connect one end of the refrigerant pipe to the vacuum pump.
- Start the vacuum pump and extract pressure from the system. The device will display the vacuum degree and elapsed time.
