• Video Recording: Taps once to start video recording, and again to stop and save.
• Library: Views, shares, or deletes stored infrared images and videos.

5.2 Instructions on Temperature Measurement Operation

The app offers various tools for precise temperature analysis:

• Center Temperature: Displays the temperature value at the middle position of the thermal image.
• Highest/Lowest Temperature: Displays the position and temperature value of the highest/lowest temperature in the global thermal image.
• Point Temperature Measurement: Tap the button, then tap on the infrared image to display a point temperature and its value. Up to three points can be displayed.
• Line Temperature Measurement: Draw a line on the infrared image to display the highest, lowest, and average temperatures along that line. Up to three lines can be displayed.
• Rectangle Temperature Measurement: Draw a rectangle on the infrared image to display the highest, lowest, and average temperatures within that area. Up to three rectangles can be displayed.
• Delete: Deletes all point, line, and frame temperature measurements.

5.3 APP Function Introduction (PC - ThermPal Software)

The "ThermPal" software for PC offers similar functionalities for analyzing thermal images:

• Online Analysis: Real-time display of infrared images, with functions such as point, line, and area temperature measurement, image settings, photo taking, video recording, and report generation.
• Offline Analysis: Open historical infrared photos to measure temperature, make annotations, change parameters, adjust the temperature bar, and generate reports.
• Chart Analysis: Display real-time temperatures in charts, including point, line, rectangle, and polygon temperature.
• Data Storage: Synchronize and store temperature data and over-temperature photo images to the computer hard drive.
• Thermal Field Analysis: Generate 2D infrared images into 3D images and display the distribution of high and low temperatures through stereoscopic images.
• Double Board Comparison: Divides the image area into two halves for comparing a standard sample area with a sample to be tested.
• Settings: Access Temperature Settings, Camera settings, Storage settings, Alarm settings, Language Settings, and About.

6. Maintenance

Proper maintenance ensures the longevity and performance of your Nohawk Thermal Camera:

• Cleaning: Do not scrub your device with diluent. Use a soft, dry cloth for cleaning.

7. Troubleshooting

7.1 Common Issues and Solutions

Q: Why is there no response after connecting the thermal imaging camera to a phone?

A: Follow these steps to identify the problem:

1. Check if the device is properly connected to your phone, or if your phone supports OTG functionality.
2. Check if OTG is available in your phone's settings and if it is ON. For most phones, OTG functions are enabled by default. If not, search "OTG" in Settings and turn it on manually. Note that the thermal imaging camera is not compatible with phones without OTG function.
3. Check if the Android version is 6.0 or above.
4. Check if you have downloaded the thermal camera app and granted necessary authorization.
5. Unplug the thermal imaging camera and reconnect it. If there is still no response, please contact after-sales personnel.

Q: Can the thermal imaging camera detect objects underwater, through glass, or a wall?

A: No. Infrared detectors mainly detect the long-wave infrared region of 8~14µm, and can only be used to measure surface temperature.

Q: Why does the temperature reading increase when the device gets closer to the object?

A: Infrared radiation attenuates when passing through the atmosphere. The longer the distance, the greater the attenuation. To ensure accuracy, go to Thermography Settings - Distance, and input the actual distance (max: 20m) to get the corrected temperature.

Q: Why is there a clicking sound? What does "shutter moving" mean?

A: The temperature of the infrared imaging will change slightly during use. Therefore, a periodic internal temperature calibration is needed. The micro motor controlled activation or deactivation of such internal calibration makes such a sound, which is known in the industry as "shutter moving".

Q: Why is the measured temperature not precise?

A: The temperature resolution of the thermal imaging camera is ±2°C. The thermal imaging camera provides an operating temperature range of -10~+50°C, and a Temperature range of -20-450°C. Please select the corresponding range in the app before measuring.

Q: What external factors will affect the infrared temperature measurement?

A: The factors are as follows:

1. Emissivity of the target object surface.
2. Ambient temperature: the object will reflect the infrared rays emitted by surrounding objects, which affects the temperature measurement of the object itself.
3. Atmospheric temperature: the atmosphere also emits infrared rays.
4. Atmospheric transmittance: the infrared rays emitted by the object are attenuated in the atmosphere.
5. Distance: the longer the distance, the greater the attenuation of the infrared rays emitted by the object in the atmosphere.
