4. Setup
4.1. Refrigerant Scale (SRC-400) Setup
- Battery Installation: The remote control for the SRC-400 scale is powered by 5 AAA batteries. Open the battery compartment on the remote and insert the batteries, observing correct polarity.
- Placement: Place the scale on a flat, stable surface. The remote can be placed directly into the designated slot on the scale for storage or detached for remote viewing.

4.2. Digital Manifold (LMG-10X) Setup
- Hose Connection: Connect the appropriate refrigerant hoses to the SAE 1/4 inch fittings on the manifold. Ensure connections are tight to prevent leaks.
- Power On: Press the power button to turn on the manifold. The display will illuminate, showing initial readings.
5. Operating Instructions
5.1. Using the Refrigerant Scale (SRC-400)
- Power On: Press the 'ON/OFF' button on the remote to power on the scale.
- Unit Selection: Use the 'UNIT' button to cycle through available units (KG, LB, OZ) until your desired unit is displayed.
- Zeroing: Place the empty refrigerant cylinder on the scale. Press the 'ZERO' or 'TARE' button to zero out the weight of the cylinder.
- Charging/Recovery: Connect the refrigerant hose to the cylinder and the system. Monitor the weight change on the display during charging or recovery processes.
5.2. Using the Digital Manifold (LMG-10X)
- Refrigerant Selection: Use the 'MODE' button to navigate through the menu and select the specific refrigerant type (e.g., R114) being used in the system.
- Pressure/Temperature Readings: The main display will show real-time pressure and temperature readings for both high and low sides.
- Superheat/Subcooling Measurement: The manifold automatically calculates and displays superheat (SH) and subcooling (SC) values based on the selected refrigerant and measured temperatures.

- Unit Conversion: Use the dedicated buttons to switch between pressure units (psi, kg/cm², kPa, Mpa, bar) and temperature units (°F/°C) as needed.
- Zeroing Pressure: If necessary, use the 'ZERO' button to calibrate the pressure sensors before taking readings.
6. Maintenance
- Cleaning: Wipe the scale platform and manifold display with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in the scale remote when the low battery indicator appears.
- Hose Inspection: Regularly inspect refrigerant hoses for wear, cracks, or damage. Replace damaged hoses immediately.
- Storage: Store the equipment in a clean, dry place away from direct sunlight and extreme temperatures when not in use.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scale not powering on | Dead batteries in remote | Replace 5 AAA batteries in the remote. |
| Inaccurate scale readings | Scale not level; Overload; External vibrations | Ensure scale is on a flat surface; Do not exceed 220 lbs; Operate in a stable environment. |
| Manifold display blank | No power; Low battery | Check power connection or replace batteries (if applicable). |
| Manifold pressure readings incorrect | Sensors need zeroing; Incorrect refrigerant selected | Perform pressure zeroing; Verify correct refrigerant type is selected. |
| 'FULL' displayed on scale | Scale overloaded | Remove excess weight; Do not exceed 220 lbs capacity. |
