3.2 Misurazione del vuoto

Connect the VGW-Mini to the HVAC or refrigeration system using the 1/4" SAE adaptor. The gauge measures vacuum from 19,000 Microns (atmosphere) down to 0 Micron with an accuracy of ±10% or ±10 Micron.

3.3 H2O Status Judgment

The vacuum meter automatically assesses the physical state of H2O by comparing the ambient temperature with the water saturation temperature corresponding to the system's vacuum level.

4. Manutenzione

4.1 Pulizia del sensore

Regular cleaning of the sensor is crucial for maintaining accurate readings. Oil or contaminants can impact accuracy. Refer to the manufacturer's guidelines for specific cleaning procedures. Generally, this involves carefully removing any debris and cleaning with an appropriate solvent like denatured alcohol, ensuring the sensor is completely dry before reassembly.

4.2 Oil Proof Film

The product includes an oil proof film inside its head. If directly connecting to a vacuum pump, this film may cause a delayed numerical display. It is suggested to remove the oil film when connecting to the vacuum pump and reinstall it when connecting to the system to prevent oil contamination.

4.3 Cura della batteria

To prolong battery life, charge the device regularly and avoid fully discharging it. Store the device in a cool, dry place when not in use.

5. Risoluzione Dei Problemi

5.1 Delayed Numerical Display

If you experience a delayed numerical display when connected directly to a vacuum pump, consider temporarily removing the internal oil proof film as described in Section 4.2. Reinstall the film when connecting to the system.

5.2 Letture imprecise

Inaccurate readings can often be attributed to a contaminated sensor. Perform a thorough sensor cleaning as outlined in Section 4.1. Ensure all connections are tight and leak-free.

5.3 Problemi di connettività delle app

Ensure Bluetooth is enabled on your mobile device and the VGW-Mini is within range. Restart both the device and the app if connection problems persist. Verify that the Elitech Tools App is updated to the latest version.
