Introduction
The Fluke ii900/ii910 is an Acoustic Imager (the Product or
Imager) that detects and locates an acoustic signature. These
www.GlobalTestSupply.com
signatures can indicate leaks in compressed air, compressed gas,
and vacuum systems.
In addition, the ii910 detects electrical discharges as well as leaks.
Examples of these electrical discharges include partial discharge
such as corona, surface tracking, and arcing. The ii910 also
identifies and locates potential mechanical issues.
The Imager has an acoustic sensor-array that aligns a soundsource heatmap with the image. The visible-light camera provides
a live-view image of the inspection area. 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 changes in sound pressure. Decibel indicates
the level of the sound (against the reference level of sound in air)
and is expressed in terms of dB SPL.
Distance to target. The distance between the leak source and the
acoustic sensor is critical. The decibel level that the Imager can
measure decreases with the square of this distance.
www.GlobalTestSupply.com
Sound Frequency / Acoustic Frequency / Frequency Band.
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 level of sound detected in all frequency ranges.
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.
LeakQ™. LeakQ is a capture mode that estimates the size of a
leak. LeakQ Scale is a scale from 0 to 10 that is an indication of
the leak size. The Imager calculates a value based on the
measured dB SPL level and the distance value. The distance
value is automatically determined or you input a value with the
display keyboard.

PDQ Mode™. PDQ Mode is a capture mode that detects and
locates potential partial discharges. The PDQ Mode indicates a
possible type of Partial Discharge (External, Internal, Tracking, or
Other), Pulse count indication/minute, and Phase-resolved Partial
Discharge Plot (PRPD plot).
Partial Discharge (PD). PD is a localized dielectric breakdown
that does not completely bridge the electrical insulation between
two conductors under high voltage.
PD types are classified into three main types:
• External discharge, or corona discharge, is the ionization of a
fluid, gas, or air surrounding a conductor that is electrically
www.GlobalTestSupply.com
charged at high voltage.
• Internal discharge occurs in voids or cavities within solid or
liquid dielectrics.
• Surface discharge tracks across the surface of different
insulation materials.
MecQ™. MecQ is a capture mode that detects and locates
potential anomalies in mechanical components as an early
identification of possible mechanical deterioration that requires
further inspection.

Capture Analysis Modes
LeakQ™ mode. The Imager is able to capture the leak data for
later use to evaluate the type of leak (quick connect, threaded
coupling, hose, open end) and estimate the size of the leak.
PDQ Mode™ (ii910 only). The Imager is able to detect, locate,
and capture potential partial discharges and evaluate the type of
partial discharge (external, internal, surface, or other). The data
includes information for later use to create pulse phase diagrams.
MecQ™ mode (ii910 only). The Imager is able to detect, locate,
and capture a picture of components that may have mechanical
deterioration and require further attention.

The capture analysis modes show on the display when the
on-device option is turned on. When on, a portion of the analysis
shows on-screen at the time of capture (see Settings and
Operating Conditions).
LeakQ™ Mode
LeakQ mode automatically determines the distance to the
target (a leak that shows inside the circle on the display).
When a leak is detected and the Imager can determine the
distance, the LeakQ value on the display gives an indication
of the size of the leak. The value is based on the measured dB
SPL value and the distance.
If a leak shows inside the circle on the display:
• Values for DISTANCE and LeakQ Scale show on the
display.
or
• NO TARGET FOUND shows on the display when no leak
is detected inside the circle.
If the Imager cannot automatically determine the distance, this
pop-up message shows on the display:
UNABLE TO ESTIMA TE DISTANCE
If the Imager is unable to determine the distance, or you want
to override the estimated distance, you can input the distance
manually.
To input the distance manually:
1. Tap on the message to open a numeric screen and enter
the distance.
The Imager uses the entered distance to calculate the
LeakQ values.
Note
Stabilize the Imager for a few moments as it calculates
the values.
2. Press the Capture button to make a more precise
calculation.

format. You can add notes, photo notes, or tags to the
image. See Memory for more information.
Note
For best results:
www.GlobalTestSupply.com
• Move the Imager around the leak to find the
highest LeakQ value. This will best reflect the
actual leak size.
• Obstacles within the circle may influence the
calculated distance and LeakQ value.
• High background noise will influence the calculated
distance and LeakQ value.
PDQ Mode™ (ii910)
PDQ Mode™ captures data from a Partial Discharge (PD) that
enables further analysis such as type of discharge and
severity. The PD must be inside the circle on the display.
When a PD is detected, the PD Count value on the display
gives an indication of the pulses generated by that partial
discharge.
The value is based on the pulses of the acoustic interference
generated by the PD:
• Values for estimated DISTANCE show on the display.
or
• NO TARGET FOUND shows on the display when no PD
is detected inside the circle.
If the Imager cannot automatically determine the distance, this
pop-up message shows on the display:
UNABLE TO ESTIMAT E DISTANCE
If the Imager is unable to determine the distance, or you want
to override the estimated distance, you can input the distance
manually. See LeakQ™ Mode.
Note
PD Count value is not directly related to the distance.
The Imager saves the still photo of the scene with overlapping
sound image and values in .PNG or .JPG format. You can add
notes, photo notes, or tags to the image. See Memory for
more information.
MecQ™ Mode (ii910)

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. Push and hold
3. Aim the Imager at the test area.
www.GlobalTestSupply.com
Ideal distance is 1 m to 8 m (3 ft to 26 ft). With good
line-of-sight, >8 m to ≤21 m (>26 ft to ≤70 ft).
4. Select a band on the frequency spectrum on the right side of
the display. See Table 4.
5. Change the width of the band by sliding the edges or move by
sliding the middle of the band.
6. 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.
High frequency peaks within the selected band may be
caused by sources other than a leak or partial
discharge. 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.
