Button Description
Calibrate ► To start the calibration, press this button. See
"Calibrating [ } 58]".
Load/Unload The lid of the test chamber can only be opened at
atmospheric pressure.
► To prevent the entry of air (and thus the amount of
natural helium contained in it) when changing the test
object, or to open the lid of the test chamber after an
aborted measurement process due to the exceeded
setpoint in the gross leak test, press this button. The test
chamber is purged for the set time.
Regenerate ► To start the regeneration of the cryogenic pump, press
this button. See "Perform regeneration [
}
72]".
Abort Aborting the ongoing process.
► For example, to stop regeneration before the end of the
set end time, press this button.
Leak Test ► To start the measurement process to determine the leak
rate, press this button. See "Preparing the measurement
[ } 60]".
Display of the leak rate
To display the measured leak rate in the units [mbar l/s] or
[atm cc/s] in the vector diagram and as a numeric value. The green measuring range
defines the good test objects. The red measuring range defines the bad test objects.
► To define the threshold value for the gross leak test, select the method editor, see
also Set the setpoint for gross leak test [ } 55]
Cathode in CHLD-Sensor ON/OFF
To switch the cathode in the CHLD-Sensor on and off.
SEM amplifier ON/OFF
To switch the SEM amplifier (secondary electron multipliers) ON and OFF.
Method in use
Displays the selected method for the current measurement process.
Display measuring progress
To display the relative measuring progress with the progress bar.
