Notes

Safety

WARN

Sources of danger include mechanical parts that can cause serious injury to persons. There is also a risk of damage to objects (e.g. damage to the device).

WARNING

Electric shock can cause death or serious injury to persons and may also endanger the function of objects (e.g. damage to the device).

WARNING

Never point the laser beam/LED beam directly or indirectly at the eye through reflective surfaces. Laser radiation can cause irreparable damage to the eye.

Introduction

The product is a thermal imaging camera that combines centre point temperature measurement with a digital image overlaid with a heat map.

The thermal imaging function eliminates the need for time-consuming measurements of individual components, as is necessary with conventional spot thermometers (radiometers). Scan a wide area to display it as a mixed digital image with a superimposed thermal image, allowing you to quickly identify temperature problems that require closer investigation.

The device has a visual camera for better identification of problem areas. This allows you to switch from the thermal image to the visual display. Thermal images and visual images can be stored on the integrated memory to create measurement reports or print out the images. The product is very user-friendly. Simply switch it on and an image will be displayed after just a few seconds. The product is particularly suitable for maintaining electrical systems, heating, ventilation and air conditioning systems and other equipment, and enables problem areas to be identified quickly.

Operation

Features

• Colour display
• The adjustable emissivity and background reflection compensation improve measurement accuracy on partially reflective surfaces.
• Hot and cold spot marking allows the user to identify the areas with the highest and lowest temperatures in the infrared thermal image
  • The device supports multiple colour palettes, and you can select different palettes for vivid images.
  • Alignment of visual and thermal image display
  • The device supports SuperIR for optimising object contours for better image display.

Operating environment

• Ensure that the operating environment meets the requirements of the device. The operating temperature of the device is -10 °C to 50 °C and the operating humidity must not exceed 95%.
  • This device can only be used safely in regions below 2000 metres above sea level.
• Place the device in a cool and well-ventilated location.
• Do NOT expose the device to high electromagnetic radiation or dusty environments.
• Do NOT point the lens at the sun or any other bright light source.
• When using a laser device, ensure that the lens of the device is not exposed to the laser beam. Otherwise, it may burn out.
  • The device is suitable for indoor and outdoor use, but must not be used in damp environments.
  • The protection class is IP 54.
  • The degree of contamination is 2.

Charging the device

Connect the supplied USB cable and connect the device to the power supply via a power adapter to charge the device.

The power supply (not included) should meet the following standards:

• Output voltage/current: 5 VDC/2 A
• Minimum output power: 10 W

Check the charging status on the power indicator:

• Red light: normal charging process
• Flashing red: error during charging
• Green light: fully charged

• The device has a built-in rechargeable battery. When charging the device for the first time, charge it for at least 3 hours while it is switched on.
• If the camera has not been used for a long time and is too low on power, we recommend charging it for at least 30 minutes before turning it on again.
• We recommend using the USB cable supplied for both charging and data transfer.

Switching on/off

Switching

Press and hold the power button for at least six seconds to turn on the device.

After switching on, it may take at least 30 seconds for the device to be ready for use.

Switching off

When the device is switched on, press and hold 📋 for about six seconds to switch it off.

Set automatic shutdown

In the Live view, press 🔍 and go to More settings > Auto power off to set the time until the device automatically turns off as required.

Set automatic sleep mode

As this manual is updated regularly, the live view may differ slightly from the version for your specific camera model. Please refer to your camera for guidance.

Your camera performs self-calibration at regular intervals to optimise image quality and measurement accuracy. During this process, the image stops briefly and you will hear a "click" sound when a shutter moves in front of the detector. The message "Image is being calibrated..." appears in the top centre of the screen while the device is calibrating itself. Self-calibration occurs more frequently during the start-up process or in very cold or hot environments.

Display settings

Setting image modes

You can set different image modes for the device.

1. You can select an image mode in the following way:

2. Go to Settings > Image settings > Image mode and select a preferred image mode.

3. Press △ in Live View to switch the image mode.

Image modes	Description	Example
Thermal	In thermal mode, the device displays the thermal image view.
Fusion	Thermal object image with visual contours.
Visual	Visual object image only.

1. When selecting fusion mode, you must select the distance under Image settings > Parallax correction according to the distance to the target so that the thermal and visual images overlap better.
2. Press to save and exit

Set colour palettes

You can use the palettes to select the colours you want. You can switch palettes in the following ways:

• Go to Settings > Colour palettes to select a specific colour palette and press 📋 to save and exit.
• Press ▼ in Live View to switch palettes.

Set level and span

Set a display temperature range and the palette will only work for targets within that temperature range. You can achieve better image contrast by adjusting the Level and Span settings.

1. In Live View, press 🔍 to display the menu.
2. Press △ and select "Level & Span".
3. Select Adjustment Mode and press to switch between automatic and manual adjustment.

• In Auto mode, the device automatically sets the display temperature range.

- In Manual mode, select Settings to open the settings menu. Press to lock or unlock the maximum and minimum temperatures, and press to set the unlocked value. Or unlock the maximum and minimum temperatures and press to increase or decrease the individual values while maintaining the temperature range.

1. Press ↻ to save and exit.

Colour distribution

The colour distribution function automatically provides various image display effects in terms of level and range. The linear and histogram colour distribution modes can be selected for different application scenarios.

1. Go to Image Settings > Colour Distribution.
2. Select a colour distribution mode.

Mode	Description	Example
Linear	Linear mode is used to detect small targets with high temperatures in a background with low temperatures. The linear colour distribution highlights and displays more details of high-temperature targets, which is useful for checking small, high-temperature defects such as cable connectors.
Histogram	Histogram mode is used to detect temperature distribution over large areas. The histogram colour distribution highlights high-temperature targets and retains details of low-temperature objects in the area. This is well suited for detecting small, low-temperature targets such as cracks.

3. Tap ⇔ to save and exit the function.
