5. Operating Instructions
The HIKMICRO H21Pro offers various functions for thermal imaging and temperature measurement.
5.1 Basic Thermal Imaging
Once powered on, the device will display a thermal image on the screen. Point the thermal imager at the object or area you wish to inspect. The screen will show the temperature distribution.
5.2 Temperature Measurement Functions
- Center Point Measurement: The device automatically displays the temperature at the center of the screen.
- Maximum/Minimum Temperature: The H21Pro supports displaying the maximum and minimum temperatures within the current field of view.
- Temperature Range: The instrument can measure temperatures from -20°C to 350°C.
- Accuracy: The temperature measurement accuracy is ±2℃.
5.3 Image Enhancement and Palettes
- 3D Noise Reduction: Improves image clarity by reducing noise.
- Image Details Enhancement: Sharpens the thermal image for better identification of objects.
- False Color Palettes: The device supports 4 kinds of false color palettes: White heat, Black heat, Iron red, and Rainbow. These can be adjusted via the menu to suit different inspection needs and preferences.
5.4 Data Storage and Analysis
The H21Pro stores full-screen temperature measurement information on the memory card. This data supports offline temperature measurement analysis when used with compatible client software.
6. Maintenance
6.1 Cleaning
- Use a soft, dry cloth to clean the exterior of the device.
- For the lens, use a lens cleaning cloth and specialized lens cleaning solution. Do not use abrasive materials or harsh chemicals.
- Ensure the device is powered off before cleaning.
6.2 Storage
When not in use for extended periods, store the HIKMICRO H21Pro in its protective carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the battery is partially charged (around 50%) before long-term storage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or battery depleted. | Charge the device fully. |
| Image is blurry or unclear. | Dirty lens; incorrect focus (if applicable); environmental factors. | Clean the lens. Ensure the target is within the optimal measurement distance. |
| Inaccurate temperature readings. | Incorrect emissivity setting; distance to target too far; reflective surfaces. | Adjust emissivity if possible. Ensure proper measurement distance. Avoid highly reflective surfaces. |
| Cannot save images. | Memory card full or not inserted correctly. | Check memory card insertion. Delete old files or replace with a new card. |
