Elitech MS-800 Series Manifold Instrument User Manual
1 Product Introduction
Welcome to the Elitech MS-800 series manifold instrument. Please read this manual carefully before use to avoid improper operation that could cause harm to you or the product. The MS-800 series manifold instrument integrates pressure-temperature mode, pressure-holding mode, vacuum mode, and data logging mode. It is suitable for daily troubleshooting, maintenance, and repair of refrigeration and HVAC systems, providing users with more real and accurate data. It significantly improves the efficiency of on-site work and can completely replace existing mechanical gauge valves. Featuring a dot-matrix LCD screen for a rich interface effect and more intuitive data viewing, it also supports an APP for viewing reports and data analysis. It allows for instant updates of commonly used refrigerants and can be upgraded via remote firmware, continuously enhancing the user experience.

7 Quick Operation Guide
7.1 Measuring Pressure and Temperature
- Press the
[Power Button]to turn on the device and enter the main interface for PT. - Hold the
[Up Arrow]and[Down Arrow]buttons for 3 seconds to unlock the refrigerant selection. - Refrigerant area blinks, short press
[Up Arrow]or[Down Arrow]to select the desired refrigerant. - Close all valves and connect the high and low-pressure sides of the product to the system being tested.
- Start the system being tested to real-time monitor the system's pressure and saturation temperature among other parameters.
Note: Ensure proper connection according to the diagram shown below.
Diagram Description: The diagrams illustrate the connection setup for both the MS-810 series and MS-870 series units to a refrigeration system. The connections involve the high-pressure side, low-pressure side, and a service port. Valves on the unit and the system are shown in specific ON/OFF states relevant to the measurement process.
7.2 Hold Pressure Measurement
- Turn on the device and press the
[Test Button]to enter the HOLD pressure interface. - Charge the system being tested with an appropriate amount of nitrogen. When the pressure reaches the target value, close the high-pressure side valve.
- Press the
[Test Button]to start the hold pressure test.
Note: Ensure the connection is made correctly according to the diagram shown below.
Diagram Description: Similar to the previous connection diagrams, these illustrate the setup for a hold pressure test. The MS-810 and MS-870 series units are shown connected to a refrigeration system, with valves positioned to perform the test after reaching a target pressure.
7.3 Refrigerant Charging
- Turn on the device and enter the PT interface.
- Connect the refrigerant tank to the middle interface.
- Close the high-pressure valve and open the low-pressure valve.
- Open the refrigerant line valve to charge refrigerant.
Note: Ensure the connection is made correctly as shown in the diagram below.
Diagram Description: These diagrams show the MS-810 and MS-870 series units connected for refrigerant charging. The refrigerant tank is connected to the central port, and the valves are configured to allow refrigerant flow into the system.
