Single Source/Multiple Sources
The Single Source mode shows less noise and reflection on the
display. Smaller leaks or partial discharges do not show when they
are close together with larger leaks or PD in the same field of view.
The Multiple Sources mode will not mask smaller leaks or partial
discharges when they are in presence of larger leaks or PD. When
in Multiple Sources mode, several markers show on the display to
indicate the peak dB level of any detected source of sound.
Note
The central marker does not show on the display in the
Multiple Sources mode. The Multiple Sources mode is
not available in MecQ mode.
Profiles
Profiles allow you to reuse the manual settings such as Frequency
band, Max dB scale and Min dB scale, and Palette.
On: A preset profile is active. The icon in the center bottom of the
display allows you to select a profile or save the current settings as
a profile.
Off: Turn off the preset profile.
Note
When you turn on and turn off the Imager, the settings
for Frequency Band, Max dB, Min dB, and Palette
reset to the values in the selected profile, not the
current settings when the unit is turned off. If no profile
is selected when the Imager is turned off, the Imager
uses the factory-default profile.
MecQ Mode (ii910 MecQ Mode only)
MecQ offers three modes to identify potential mechanical areas of
interest:
Mode 1: 30 kHz mode (default). This mode automatically
activates the 30 kHz frequency band.
Mode 2: User selection mode. In this mode you can select any
frequency range between 2 and 100 kHz
Mode 3: Fixed Multi mode. This mode automatically activates
five predefined frequency bands.
Palette
Select the palette for the acoustic image. The color palettes offer
an equal, linear presentation of colors for the best presentation of
data detail. Or you can switch the live visual camera to greyscale
mode.
Markers
When the Centerpoint Marker is On, the dB level of the
Centerpoint shows on the display as value on the center of the
display.
Note
The display shows the dB value of the selected
frequencies as received in the center of the Field-of-
View. This is not the dB value of the sound source.
Settings
The Settings menu shows all the available settings for adjustment.
