| Image is too dark | Brightness or contrast level is too low | Adjust the brightness or contrast |
| Color bars appear on the display or the image disappears | The device was exposed to static charges during operation | When the exposure to static charges is over, the device may either reboot automatically or require to be switched off and on again |
| The image of the object being observed is missing | You are looking through glass | Remove the glass or change the viewing position to avoid it |
| Poor image quality / reduced detection distance | These problems may occur during observation in adverse weather conditions (snow, rain, fog, etc.) | |
| When the device is used in low temperature conditions the image quality is worse than in positive temperatures | In positive temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high temperature contrast. Consequently, the image quality produced by the thermal imager will be better. In low-temperature conditions, objects being observed (background) will cool down to roughly the same temperature, which leads to a greatly reduced temperature contrast and a degraded image quality. This is normal for all thermal imaging devices | |
| Rangefinder does not measure distance | In front of the receiver lens or emitter lens there is an object that prevents signal transmission. | Make sure that: the lenses are not blocked by your hand or fingers; the lenses are clean. |
| The device vibrates when measuring | Hold the device level while measuring | |
| Distance to the object exceeds 1000m. | Choose an object at a distance closer than 1000m | |
| Low reflection ratio (i.e. leaves of trees) | Choose an object with a higher reflection ratio | |
| Large measurement error | Inclement weather conditions (rain, mist, snow) | |
Repair of the device is possible within 5 years.
