Introduction

The Fluke ii900/ii910 is an Acoustic Imager (the Product or
Imager) that detects and locates an acoustic signature. These
signatures can indicate leaks in compressed air, compressed gas,
and vacuum systems.

The ii910 also detects electrical discharges as well as leaks.
Examples of these electrical discharges include partial discharge
such as corona, surface tracking, and arcing.

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.

Acoustic Imager

Before You Start

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.

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 is a capture mode that evaluates the type and
severity of an electrical discharge. The PD count value is an
indication of the number of pulses that the Imager can detect.

Partial Discharge (PD). PD is a localized dielectric breakdown
that does not completely bridge the electrical insulation between
two conductors under high voltage.

Corona Discharge (CD). CD is a subtype of PD that results from
the ionization of a fluid, gas, or air surrounding a conductor that is
electrically charged at high voltage.
