Vacuum Degree
Note: This vacuum function uses a non-professional vacuum sensor, which can only be used to roughly
observe the vacuum state of the system. In order to accurately measure the vacuum value of the system, it is
not recommended to use this instrument, please use a professional vacuum meter.
3.4 Pressure Leak Test Mode (HOLD)
1.Connect the refrigerant hose on the high-pressure side to the tested system and close
the high-pressure valve.
The high-pressure side channel is used for pressure leakage test of the system.
2.Enter the pressure leakage test:Press
3.Start leakage test:Press
The timer counts every minute.
After starting pressure holding, the initial value is displayed in the low pressure area and the current value
is displayed in the high pressure area.
4.End the leakage test:Press the
5.Check the test data and analyze the system leakage.

Note: The instrument has its own temperature compensation function, which can perform the tightness test
of the compression system. Leak analysis is performed by measuring system pressure and ambient
temperature over time. If the temperature compensation function is not required, you can turn it off by setting
menu.
