Message window
To display status messages in the yellow field, e.g. "Leak Test done" (measurement
process completed); the operating mode e.g. "Standby" and the time measuring
progress.
System diagram
Displays current system conditions and parameters, such as temperature, pressure,
leak rate, and system components.
Selection menu
To select the following modes:
• MID
In the "MID" (Multiple Ion Detection) mode, you can carry out a simultaneous
measurement signal acquisition for several masses (= gases) over time.
• Bar
You can measure the signal intensities of selected masses in "Bar" mode and
display them as a bar graph.
• Scan
In "Scan" mode, you can perform continuous (analog) sampling of the signal
intensities across the measuring axis.
• Method
You can start the method editor . See "Select method [
}
49]".
• Recipe
You can start the recipe editor to configure the mass spectrometer (CHLD-
Sensor). See "Select method [ } 49]".
Parameter Description
He-TL Slope The test leakage signal slope measured during the
calibration in unit of measurement [A/s].
He-Sample Slope The helium signal slope determined by the measurement
of the test object in the unit of measurement [A/s].
He-BG Slope The measured helium background signal slope during a
calibration in unit of measurement [A/s].
Gas 2 amplitude Signal amplitude of a second measured gas (in multi-gas
mode).
S/B 100 ratio Ratio of helium test leak signal slope to
helium background signal slope during the last calibration.
Net-TL Slope Difference of helium test leak signal slope and
helium background signal slope during last calibration in
unit of measurement [A/s].
