Introduction
The Fluke ii900 is a Sonic Industrial Imager (the Product or
Imager) primarily used to detect and locate leaks in compressed
air, compressed gas, and vacuum systems. The Imager has a
visible light camera that captures a live-view image of the
inspection area. An acoustic sensor-array aligns a sound-source
heatmap with the image. Capture and save still image files and
video files from the inspection for documentation and reports.
A rechargeable battery powers the Imager. The Imager includes
an external battery charger with power adapter and
country-specific cables.
The Imager has a USB-C port that connects to a PC for file
download and firmware updates.

Terms to Know
Use this section to familiarize yourself with these terms that are
unique to this Imager and sound pressure measurements.
Decibel (dB) Sound Pressure Level (SPL). The unit of
measurement for sound pressure changes. Decibel indicates the
intensity (loudness) of the sound and is expressed in terms of
dB SPL.
Distance to target. The distance between the leak source and the
Imager acoustic sensor is critical. The decibel level that the Imager
can measure decreases with the square of this distance.
Sound Frequency / Acoustic Frequency / Frequency Band.
The frequency indicates the pitch of sound. The frequency
corresponds to the number of sound vibrations/second and is
expressed as Hertz (Hz) or thousands of Hertz (kHz).
Frequency Range
Audible (up to 20 kHz). The range that human ear can
perceive sounds.
Ultrasonic (above 20 kHz). Certain issues (leaks, electrical
discharges, mechanical failures) generate sound signatures in
ultrasonic ranges. The human ear cannot perceive the
ultrasonic range that the Imager can detect.
Frequency Selection / Frequency Filtering / Selected
Frequency Band. Select a frequency band for measurement and
visualization of sound. When a frequency band is selected, any
sound outside of that range is filtered and not shown or
considered.
Background Noise. The noise that exists in the surroundings that
the microphone sensors detect along with the sound sources of
possible leaks. Generally, background noise is higher in lower
frequencies. In noisy environments, select higher frequencies to
help discriminate the leak sounds.
Frequency / Spectrum Graph. A graphic chart on the display
shows the intensity of sound detected in all frequency ranges up to
52 kHz.
Frequency Spike. Spike in the frequency / spectrum graph that
indicates a significant source of sound in this specific frequency. If
this spike is within the frequency selection, the Imager visualizes
the source on the display.
Field-of-View (FOV). What is detected by the Imager at a
particular position and orientation in space.
Sound Reflections. Sound signals reflect, particularly on smooth
and flat surfaces. In certain conditions, the Imager shows on the
display a hot spot from the source of noise and one or more hot
spots from reflections.

Acoustics
The Acoustics menu shows all the available settings for
adjustment.
Show dB Scale: On or Off
You can choose to show or hide the dB scale. Turn off the dB
scale to see a larger visual area on the display.
Min dB / Max dB
The minimum/maximum decibel settings determine the sound
level (intensity) that shows on the SoundMap. Decibel level
thresholds help you to visualize leaks in challenging conditions, for
example, very small leaks or a lot of background noise in the same
frequency range as a leak. For more information, see Frequency
Profiles.
Auto On: Automatically adjusts the Color Palette Scale to the
minimum/maximum decibel value for the received sound pressure.
Auto Off: The Color Palette Scale is a user-defined minimum/
maximum decibel value. Levels above the maximum value show
on the display with the same color as the maximum value. Levels
below the minimum value do not show on the display.
Decibel Scaling
Use the slider to manually adjust the minimum and maximum in
decibel values of the Color Palette Scale.
Frequency Profiles
A frequency profile is the band of frequencies that you select as an
overlay on the visual image. The high and low frequency defines
the band.
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.
Palette
Select the palette for the acoustic image. The palettes offer an
equal, linear presentation of colors for the best presentation of
data detail.
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.

Basic Operation
The Imager works much like a point-and-shoot camera.
W Caution
Do not place hand on or obstruct the acoustic
sensor. Always use the sensor cover when the
Product is not in use.
1. Remove the sensor cover before use.
2. Aim the Imager at the test area.
Ideal distance is 3 m to 7.6 m (10 ft to 25 ft). With good
line-of-sight, >7.6 m to ≤21 m (>25 ft to ≤70 ft).
3. Select a band on the frequency spectrum on the right side of
the display. See Table 4.
4. Change the width of the band by sliding the edges or move by
sliding the middle of the band.
5. The optimum band depends on the environment and
application. As an example for finding air or gas leaks, start
with a band at 35 kHz and width that spans 5 kHz.

Note
High frequency peaks within the selected band may be
caused by sources other than a leak. In this case,
move the band to another frequency range.
If a strong source of sound is off the field-of-view, the display
shows a circular pattern (flower) of hot spots on the
SoundMap. In this case, scan around for the source of
sound.
6. When the area of interest clearly shows, push the Capture
button. The Imager saves the image to memory.
Tip: Sound signals reflect, particularly on smooth and flat
surfaces. In certain conditions, the Imager shows a steady spot on
the source of noise and one or more steady spots from the
reflections. Move the Imager around to help discriminate the sound
source from the reflections. The sound source remains in the
same location, while reflections will move.
For more information about how to view the images in memory,
see Memory.
File Transfer
To transfer saved files from the Imager to a PC:
1. Use the provided USB cable to connect the Imager to the PC.
A USB drive is added to the list of drives on your PC.
2. Open the added USB drive to view the saved images or video
files.
3. Copy the files you want to the local PC drive.
4. When transfer is complete, remove the USB drive from your
PC.

Maintenance
The Imager does not require routine maintenance.
W Caution
The optical surfaces of the lens are equipped with
high-quality optical layers. Avoid any contact with
these surfaces and protect these surfaces against
dirt and damages.
How to Clean the Case
Clean the case with a clean, damp cloth. Do not use abrasives,
isopropyl alcohol, or solvents to clean the case or lens/window.
Acoustic Sensor Care
Always keep the Acoustic Sensor protected with the provided
cover when the Imager is not in use. Avoid grease or liquids on the
microphones. If the microphones are dirty or clogged, carefully
clean with low air pressure from a compressed air duster at 25 cm
to 30 cm (10 in to 12 in) distance. Avoid too much air pressure.
When you turn on the Imager, it does a self-check routine that
detects faulty microphones. If you see a warning message to
service the Acoustic Sensor when you turn on the Imager, clean
the microphones with an air duster, restart the Imager, and check if
the message continues. If yes, contact a Fluke Service Center.
