2) It shall not exceed the selected measuring range.
3) Use this setting as the leak detection pressure point.
4) The pressure control set point value during the test.
Set the waiting time
1) Select the internal range: After the control pressure is stable during the execution (the real-time pressure value
turns green) and it switches to measure mode and starts the countdown of the waiting time.
2) Select the external pressure module: Waiting time will be counted down after execution begins.
3) Enter the test time after the waiting time ends.
Set the test time
1) Select the internal range: After entering the test time, start the countdown, implement the test, and stop the test
after the time reaches 0.
2) Select the external pressure module: Same as the internal range.
Pressure type
1) Some devices can switch the gauge pressure and differential pressure.
2. Execution
Internal range
1) Control the pressure with the set pressure value as the target value.
2) After stabilization (the real-time pressure value turns green), stop the control and switch to the measurement mode,
and count down the waiting time.
3) Record the pressure at the end of the waiting time as the starting pressure.
4) Start the test, count down the test time, and start to calculate the real-time leakage amount at the same time. The
