LEAKSHIELD
After leaving this page, you will reach the "Standby" section.
When booting from standby, no data can be sent to LEAKSHIELD via USB yet. The-
refore LEAKSHIELD needs defaults for the operating point of the pump. You can
select this data via speed and flow defaults. In addition, current values can be
taken from the assigned data source. If you do not know the data, you should not
activate a reduction of the vacuum in standby in the following option
In the standby of the PC the negative pressure can be reduced significantly if the
pump is switched off with the PC. To enable this, you can activate the correspon-
ding function here. The negative pressure in this condition can also be selected.
Now switch to the LEAKSHIELD "Mode" page.
You can now select the operating mode of LEAKSHIELD. As a most common rule,
the "SHIELD" mode should be selected. If the vacuum of LEAKSHIELD is not suffi-
cient to protect your system (too strong pump, several pumps), you can use the
mode "MONITOR". This will be indicated by corresponding warnings in the upper
part of the page.
The "RELEASE" mode only leads to a pressure equalization to the environment.
You will then be taken to a "Summary" of the selected settings and can check them
once again. Possible notes and warnings are displayed at the top of the table.
To change settings once again, you can navigate through the pages by pressing
the arrow icons. The checkmark symbol on the Summary page transfers the set-
tings to your LEAKSHIELD. If you cancel the wizard by clicking the "X" icon (top
right), the previous settings will be saved.

10.2. The "Test" action

In the Test mode, the desired negative pressure is requested first. You can perform
a leak test with negative pressures between 80 and 450 mbar.
Then LEAKSHIELD starts to prepare the test and to create the negative pressure.
Once this process is complete, LEAKSHIELD will show you a graph of the pressure
change over time. You can use the "Reference" button to select the current pressu-
re as a reference. In addition, the data source of the diagram can be changed.
The absolute current negative pressure, the pressure difference to the reference va-
lue and the current pressure change are available for selection.
With the mouse you can enlarge areas in the diagram.
By pressing the "Cancel" field, you leave the test mode again.
