When not in use the device should always be placed securely inside the carrying

9-2 Inspection Techniques
9-2-1 Modes
Modes are useful for locating different types of sound sources by limiting the
frequency range of sound sources displayed on screen. Background noise,
e.g. traffic or factory noise, is often dominant at low frequencies, while many
interesting phenomena have higher frequencies. Typically, the higher the
frequency range is, the more local the sources of interest are - even in the
presence of a lot of background noise.
The device marks the highest frequency, up to 3, with a crosshair.
It is best
practice to do more in-depth analysis on the marked region as this can indicate
a leak or discharge.
