3. Inisyal Enstalasyon
3.1 Debake
Carefully remove the Xetron LMG-10X and its accessories from the packaging. Verify that all components listed in the 'What's in the Box' section (Figure 1.2) are present and undamaged.
3.2 Limen
Insert the required batteries (refer to Specifications for type and quantity) into the battery compartment located on the rear of the unit. Press and hold the power button (⏻) to turn the device on. The LCD screen will illuminate.
3.3 Connecting Temperature Probes
Connect the two wired temperature clamp probes to the designated ports on the manifold. Ensure a secure connection. These probes are essential for accurate superheat and subcool calculations.
3.4 Konekte Tiyo yo
Attach your standard 1/4" SAE threaded refrigerant hoses to the manifold's ports. Ensure all connections are tight to prevent leaks. The manifold features a convenient suspension hook for easy placement during use.
4. Operasyon Enstriksyon
4.1 Basic Measurements (Pressure, Temperature)
Once powered on and connected, the LMG-10X will display real-time pressure readings for both high and low sides, along with temperatures from the connected probes. The unit automatically compensates for temperature variations.
4.2 Superheat and Subcooling Calculation
The LMG-10X automatically calculates superheat and subcooling values based on the selected refrigerant and the measured pressures and temperatures. These values are displayed prominently on the screen.

4.3 Mezi vakyòm
The device can perform vacuum measurements, essential for evacuating HVAC systems. Follow standard industry procedures for vacuuming, using the manifold to monitor the vacuum level.
4.4 Pressure Holding Test
Utilize the pressure holding test function to verify system integrity and detect leaks. The manifold will monitor pressure changes over a set period.
4.5 Seleksyon frigorigènes
Peze a MÒD button to cycle through the available refrigerants in the built-in database. Select the refrigerant corresponding to the system you are working on for accurate calculations.
4.6 Seleksyon Inite
The LMG-10X supports various units for pressure (psi, kg/cm², kPa, Mpa, bar) and temperature (°F/°C). Use the appropriate button (refer to the device's interface) to switch between desired units.
4.7 Zeroing Pressure
Before taking measurements, it is recommended to zero the pressure sensors. Press the ZERO / ⏻ button briefly to calibrate the pressure readings to zero in ambient conditions.
5. Antretyen ak Swen
5.1 Netwayaj
Siye inite a avèk yon mou, damp cloth. Do not use abrasive cleaners or solvents. Ensure the display and buttons are free from dirt and debris.
5.2 Depo
Store the LMG-10X in a clean, dry environment, away from extreme temperatures and direct sunlight. It is recommended to store it in its original packaging or a protective case to prevent damage.
5.3 Ranplasman batri
When the battery indicator shows low power, replace the batteries promptly. Open the battery compartment on the back of the unit, remove old batteries, and insert new ones, observing correct polarity.
5.4 Kalibrasyon
While the device is factory calibrated, periodic re-calibration may be necessary to maintain accuracy, especially after significant impacts or prolonged use. Refer to the manufacturer's guidelines or contact customer support for calibration services.
