5. Setup
Follow these steps for initial setup of your VGW-10X vacuum gauge.
- Charge the Device: 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.
- Power On: Press and hold the power button (usually located on the side or front) for a few seconds until the display illuminates.
- Unit Selection: 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. Operating Instructions
This section outlines the basic operation of the vacuum gauge for taking measurements.
Figure 6.1: Clear LCD Screen Reading
- Connect to System: 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.
- Start Vacuum Pump: Activate your vacuum pump to begin evacuating the system.
- Monitor Readings: 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.
- Power Off: After completing your measurements, disconnect the gauge from the system and press and hold the power button to turn off the device.
7. Bluetooth APP Control
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
- Download the App: Search for the Xetron vacuum gauge app on the App Store (for iOS devices) or Google Play (for Android devices).
- Enable Bluetooth: Ensure Bluetooth is enabled on your smartphone or tablet and on the VGW-10X device.
- Connect to Device: 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.
- Monitor Data: The app allows you to browse real-time measurement data, view graphs, and monitor the progress of your vacuum process.
- Export Reports: Generate and export measurement reports directly from your smartphone or tablet.
- Offline Recording: Utilize the offline recording function to log data even when not actively connected to the app, allowing for later review.
8. Advanced Features
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. Temperature Compensation
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.
9. Maintenance
Proper maintenance ensures the longevity and accuracy of your Xetron VGW-10X.
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the sensor port is free of debris.
- Sensor Protection: Always keep the protective cap on the sensor port when the device is not in use to prevent contamination.
- O-Rings: Regularly inspect the O-rings on the fitting for wear or damage. Replace them if necessary to maintain a leak-free connection.
- Battery Care: Recharge the battery regularly, even if the device is not used frequently, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Storage: Store the device in its protective bag in a cool, dry place away from direct sunlight and extreme temperatures.
