6.2.8 Setting the audio alarm
WARNING
Damage to hearing due to loud audio
The alarm level of the device can exceed 85 dB(A).
► Set the volume up to a maximum of "12” (XL3000flex).
► Use suitable hearing protection at volume settings above "12".
► With the XL3000flexRC, the actual volume depends on what you plug into the
CU1000's headphone jack.
Volume of the headphones or active speaker
--- No sound
Proportional: The frequency of the audible signal is proportional to the bar graph
display or diagram height. The frequency range is 300Hz to 3300Hz.
Setpoint: The pitch is proportional to the leak rate. The signal sounds if the leak rate
exceeds the selected trigger value.
Pinpoint: The sound of the acoustic signal changes its frequency within a specific
range of leak rates. Range: A decade below the selected trigger threshold up to one
decade above. The sound keeps at a constant low and a constant high frequency
below and above this range, respectively.
Trigger: If the selected trigger threshold is exceeded, a two-pitch signal sounds.

alarm mode
Behavior with warnings or error messages: If the touch screen shows a warning or an
error, then a two-pitch signal sounds simultaneously.

Selecting a cathode
The mass spectrometer includes two cathodes. In the factory setting the device uses
cathode 1. If it is defective, the device automatically switches to the other cathode.
With this setting it is possible to select a certain cathode.
