(unauthorized modications or repairs will cause problems at

I II
your own risk).
Caution
• Protect the acoustic sensor array from stains, dust, and liquids
that could aect the performance of the acoustic imaging
camera or even cause permanent damage.
• Avoid using the product in humid, dusty, extremely hot, or cold
environments. For humidity requirements see the product
parameters table.
• It is strongly recommended to use the original power adapter.
The power adapter requirements are listed in the product
specication sheet.
• To prevent the potential risk of data loss, always copy (backup)
data to the computer.
• When storing the acoustic camera, it is strongly recommended
to use the original box and store it in a cool, dry, well-
ventilated environment free from strong electromagnetic
elds.
• When shipping the camera, it is strongly recommended that it
be shipped in the factory packaging for protection.

Quick Start
Follow these steps:
1. Place the battery in the battery compartment of the sound
camera.
2. Charge the battery to full capacity before starting the camera
for the rst time.
3. Press the power button to turn on the camera.
4. Select the detection mode according to user's need. (for more
details, see the next section)
5. Aim the camera at the target object.
6. Press the Photo button once to freeze the image. In this state,
users can modify the le name, add text notes, bookmark, or

Operational Tips
Frequency ltering
The Fast Fourier Transformation (FFT) graph on the right presents
the frequency and amplitude of current sound signals. Users can
rene the analysis by adjusting the red box on the graph, isolating
the target signal and minimizing interference from other noise.

14 丨 FOTRIC TD3 Series Quick Start Manual
Gas leakage evaluation
To initiate leakage detection mode, navigate to Settings ->
Detection and select ‘Leakage Mode.’
For precise leakage assessment, accurately complete the
‘Parameters Cong’ table with the relevant details.
The correction factor is used to reconcile any dierences between
the calculated and the actual measured leakage rates, which may
arise from variables such as leakage shape, ambient humidity, and
background noise.
The power ratio reects the energy required to compress a unit
volume of the specied gas, which is essential for a comprehensive
evaluation.
The ‘Evaluation’ option within the display mode is accessible
only after selecting ‘Leakage Mode.’

FOTRIC TD3 Series Quick Start Manual 丨 15
Within the ‘Evaluation’ interface, the camera provides an
estimate of the annual cost associated with the detected leakage.

16 丨 FOTRIC TD3 Series Quick Start Manual
Partial discharge detection
To engage the partial discharge detection mode, navigate to
Settings -> Detection and choose ‘Partial Discharge Mode.’
In this mode, the Phase Resolved Partial Discharge (PRPD) graph is
displayed in the top right corner of the screen. Click on the graph
for an expanded view. When partial discharges are detected, the
PRPD graph will plot the pulses in a sinusoidal pattern, indicating
the phase angle and magnitude of each discharge occurrence.
The PRPD graph is a powerful diagnostic tool in acoustic cameras,
as it allows for the visualization of discharge patterns over time.
This visual representation helps to distinguish between dierent
types of discharges and to identify problematic insulation in
electrical equipment.
