The system comes with three common working modes: refrigerant pressure mode,
vacuum percentage mode,leak detection mode. The interfaces of different working
modes are as follows:
REFRIGERANT PRESSURE MODE
It’s used for charging the refrigeration system with refrigerant, as well as real-time displaying curent vacuum pressure, temperature, and type of refrigerant
VACUUM PERCENTAGE MODE
It’s used for charging the refrigeration systems.
Real-time display of current vacuum level.
LEAK DETECTION MODE
It’s for detecting pressure leaks in refrigeration systems, with real-time display of current vacuum pressure, leak pressure and work time.

MAINTENANCE AND MAINTENANCE
1. Please operate according to the requirements of operating instructions or the
guidance of professional personnel.
2. The digital gauge should be keept clean, the display screen should be bright and
clear, so that the data on the display screen clearly.Use slightly alkaline detergent
or soapy water to wash the case and connector.
3. The pressure gauge is perishable goods,need to checking regularly to ensure its
4. Handled gently , to prevent shock and fall.
5. After use, please close all the button, to improve the service life .
6. Plug the joint when not use,to prevent foreign body from entering, clean and
replace regularly refrigerant tube, remove dirt and impurities in valve.
