Setting the audio
alarm
Output of an acoustic signal depending on the leak rate
--- 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.
Control unit Settings > Set up > Control unit > Audio > Audio 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.
Automatic switch off
of the touch screen
The touch screen can be switched off automatically after a specific time without any
operation to save energy.
