2. With the change of external atmospheric pressure or air flow and real-time jump. Display accuracy of 0.001kPa.
3. Inflatable:The icon shows inflatable when the airtightness tester is connected to the outside world and the air pressure can be output directly.
4. Pressure Adjustment: The icon shows that when the pressure is adjusted, the instrument cuts off the connection with the outside world, and the airtightness tester is in a self-closed state, which can be used to adjust the testing pressure. It can also be used to check the current instrument pressure.
5. Positive pressure: the instrument blowing, output positive pressure. Negative pressure: The instrument pumps air and outputs negative pressure.
6. Manual Exhaust: When the airtightness tester and fixture are closed, if there is pressure inside, you can manually exclude the internal air pressure.
7. Calibrate to zero: the air tightness tester is connected to the outside world, with the current atmospheric pressure as the reference zero point, the calibration point is the same as the current atmospheric pressure.
8. These are the parameters of the airtightness tester adjustment method, has been understood, please note that the parameters of the airtightness tester can only be set and adjusted by the technical engineers, quality engineers, the operator does not have the right to set and change the parameters.
9. (※Note: After the completion of the adjustment of pressure, the icon point back to the inflation mode after the return to the main menu interface.
