Proportional The frequency of the audible signal is
proportional to the bar graph display or
diagram height. The frequency range is
300 Hz to 3300 Hz.
Setpoint The pitch is proportional to the leakage rate.
A signal sounds if the leakage rate exceeds
the selected trigger value.
Pinpoint The sound of the acoustic signal changes its
frequency within a specific range of leakage
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.
