Built-in89 kinds of refrigerant NIST: According to American NIST standard. Power Supply:4pcs 1.5V AA / LR6 batteries (Battery not included). Refrigerant hoses connection and valve operation method of Vacuum Test.
Close blue valve tightly and do not connect any hoses to the corresponding inlet. Connect the vacuum pump to the vacuum pump inlet of the refrigerant gauge with the yellow hose. Open the red valve, connect the device under test with the corresponding red hose, and then you can start the vacuum operation. Note: In the vacuum operation, the blue valve does not work, only the red valve does. The blue valve needs to be closed.If the blue valve is not closed, the air pressure will escape from the blue valve and cause a leak, and the test data will be inaccurate.
