Acoustic Imager
UT568A Acoustic Imager User Manual
Warranty and Calibration
Within two years from the purchase date of this product, Uni-Trend will provide
free warranty service for the abnormal or fault caused by product quality
problems. This free warranty service does not apply to problems caused by
improper use and drop.
In case of product failure caused by improper use or accidental drop, Uni-Trend
promises to provide maintenance service at cost price.
The product has been calibrated before leaving the factory. However, in the
process of long-term use, it is recommended to send the product to the
manufacturer every 2 years for calibration, detection and maintenance.
Introduction
The acoustic imager supports ultrasonic frequency band. The product uses the
microphone array beamforming technology to acquire the distribution data of
sound sources, and collects videos and images in real time with the HD camera.
By fusing the distribution data of sound sources with videos and images, the
changing sound sources are dynamically shown on the display.
The acoustic imager can quickly detect possible pressurized gas leaks and
vacuum leaks on noisy industrial sites. When the product is used in power
system, it can rapidly identify potential partial discharge fault points.
The acoustic imager's housing is all aluminum alloys. So the product is rugged
and can be used in complex and changeable operating environments.
The product is easy to operate. Most test requirements can be satisfied only by
adjusting its frequency range and dynamic range. The product has image and
video modes for data recording. It can be inserted into a large-capacity TF card
to save and export the test results.
Safety Information

z Do not charge the product at a high temperature (exceeds 45ȭ).
z Please stop using the built-in lithium battery if it leaks.
z If the leakage gets into eyes, rinse with water and seek medical
attention immediately.
z If the leakage gets on the skin, rinse immediately with water.
Terminologies
USB Power Delivery (USB PD):
USB PD is a power transfer protocol based on USB3.1 that can transmit higher
power via USB interface.
Sound pressure level (SPL):
A physical quantity used to express the size of a sound wave. Its unit is decibels
(dB). Generally, it can be represented by dB SPL.
Audible frequency range:
The range (20Hz to 20kHz) that human ear can perceive sounds.
Ultrasound:
Ultrasound generally refers to the sound with a frequency higher than 20kHz
that cannot be perceived by human ears.
Acoustic image:
Acoustic image refers to the two-dimensional data table that represents the
intensity distribution of sound sources in the spatial plane after the signal
collected by the microphone array is calculated by the sound source location
algorithm.
Color palette:
Color palette is the color data used by the cloud image for color mapping.
Acoustic cloud image:
The SPL data of each resolution point on the acoustic image is mapped to a
certain color number on the color palette according to the conversion formula
to form a color image, which is then fused with the visible image to form an
image.
Test spectrum range:
After selecting a frequency range supported by the product, the product will only
measure and display the acoustic cloud images within the frequency range, and
the sound outside the range will not be displayed.
Frequency spike:
Spike in the spectrum graph that indicates a significant source of sound in this
specific frequency.
Dynamic range:
Dynamic range is the scale of the sound source intensity that can be displayed
on an acoustic image.
Field of view:
For a camera, field of view refers to the angle formed by two diagonal points
