5. Installation
Follow these steps for initial setup of your VGW-10X vacuum gauge.
- Chargez l'appareil : Before first use, fully charge the built-in lithium battery using the provided charging cable. A full charge can provide up to 20 hours of operation.
- Attach the Fitting: Screw the SAE 1/4" metal fitting onto the vacuum gauge securely. Ensure the O-ring is properly seated to prevent leaks.
- Mise sous tension : Press and hold the power button (usually located on the side or front) for a few seconds until the display illuminates.
- Sélection de l'unité : Briefly press the unit button (if available, or refer to the app for selection) to cycle through the available vacuum units (microns, mTorr, inHg, Pa, Torr, kPa, mbar, psia) and temperature units (°C/°F).
6. Mode d'emploi
This section outlines the basic operation of the vacuum gauge for taking measurements.
Figure 6.1: Clear LCD Screen Reading
- Connectez-vous au système : Connect the vacuum gauge (with the attached fitting) to the vacuum pump or the system port where you intend to measure vacuum. Ensure all connections are tight to prevent leaks.
- Démarrer la pompe à vide : Activate your vacuum pump to begin evacuating the system.
- Lectures du moniteur : The vacuum gauge will display real-time vacuum values. The response is fast and sensitive, allowing for precise monitoring of deep vacuum levels.
- Observe Temperature: The device also displays ambient temperature (Tamb) and water saturation temperature (TH2O), which can help in determining the presence of moisture in the system.
- Éteindre: After completing your measurements, disconnect the gauge from the system and press and hold the power button to turn off the device.
7. Contrôle via application Bluetooth
The Xetron VGW-10X can be connected to a smartphone or tablet via Bluetooth for enhanced monitoring and data management.
Figure 7.1: Xetron Mobile Application Interface
- Téléchargez l'application : Rechercher the Xetron vacuum gauge app on the App Store (for iOS devices) or Google Play (for Android devices).
- Activer Bluetooth : Ensure Bluetooth is enabled on your smartphone or tablet and on the VGW-10X device.
- Connectez-vous à l'appareil : Open the app and follow the on-screen instructions to search for and connect to your VGW-10X. The Bluetooth icon on the gauge display will illuminate when connected.

8. Fonctionnalités avancées
8.1. Understanding H2O Saturation
The VGW-10X can help assess the physical status of H2O in a cooling system by comparing ambient temperature and water saturation temperature.
Figure 8.1: H2O Status in Cooling System
By measuring both ambient temperature (Tamb) and the water saturation temperature (TH2O) corresponding to the vacuum level, the gauge can automatically determine if H2O is likely in a liquid or vapor state within the system. This feature is crucial for ensuring thorough dehydration during evacuation processes.
8.2. Compensation de température
The device incorporates an advanced ambient compensating design to maintain accuracy across varying temperature conditions.
Figure 8.2: Temperature Compensation for Accuracy
This feature automatically compensates for temperature fluctuations, ensuring consistent and reliable vacuum measurements without the need for manual adjustments by the user.
