4. Calibration mode
In this menu item you can select the calibration mode.
A - Automatic calibration every 2 minutes
- M - Manual calibration triggered by the user by a long press on the F key.
- S - Silent calibration triggered by the user by a long press on the F key.
During use, the image quality gradually decreases due to the changing background temperature of the sensor. This is compensated for by calibrating the sensor at regular intervals. For this purpose, an internal aperture is closed for a short time and the remaining signal is subsequently subtracted from the image signal as background noise.
You will recognise the calibration process by a quiet clicking sound and you will see the last image signal as a still image during this time. When the unit is switched on, several calibrations are automatically performed in the first few seconds, regardless of the calibration mode selected.
- In M mode, you determine the timing of the calibration with the internal shutter yourself. Perform a manual calibration if you notice a deterioration in picture quality that manifests itself in the form of increased picture grain or streaking.
- You trigger the S mode in the same way as the M mode. However, the internal shutter is not used, so this process is completely silent.
Notice: Cover the front lens during the calibration process. Otherwise you will see a superimposed "ghost image".
5. Input mode
Input mode allows you to select which functions are controlled directly by a click or a long press on a button, so that you do not have to call up the menu first.
For more information, see the chapter "Input Modes" with details on the setting options in each mode.

Check the charge level every 6 months.
15. TROUBLESHOOTING
This overview contains a list of the most common problems that may occur when using the unit.
Carry out all recommended checks as described in the table.
If an error occurs that is not listed in the table or if you cannot rectify an error yourself, please contact Liamke Service. Contact details: see back page
KEILER
| Malfunction Possible reason | Remedy | |
| The thermal imager cannot be switched on. In the starting process, the KEILER switches off again after the start logo has been displayed. | The battery is not sufficiently charged. | Charge the battery for half an hour before switching the unit on again. |
| The device cannot be powered by an external power source. | The external power source is not strong enough. | Use an external power source with a min. charging current of 5 V / 2 A. |
| The USB cable is damaged. | Replace the USB cable. | |
| The battery is very slow to charge. | Using a power supply unit with insufficient power. | Use only the power supply unit supplied. |
| The device is not switched off. | Switch the device off (OFF) so that charging works reliably. | |
| The battery is deeply discharged. | Charging takes a significantly longer time for deeply discharged batteries. | |
| The image is blurred, with thin vertical lines or shadows. | Calibration needed. Perform an image calibration. | |
| After calibration, a "ghost image" can be seen super-imposed on the scene. | Calibration mode S was selected and the front lens was not covered during calibration. | Perform a repeat calibration with the front lens covered. |
| Low image quality / reduced detection range. | These problems can occur under adverse weather conditions (high humidity, snowfall, rain, fog, etc.).During long periods of constant weather conditions without sunshine, and especially in rainy weather, the observed objects converge to approximately the same temperature, so that the temperature difference is considerably reduced, and the image quality suffers as a result. This circumstance is due to physical causes and is not a defect of the thermal imager. | |
| Photo or video recording does not work. | 20 seconds have not elapsed after the unit was booted up. | Wait 20 seconds after switching on the unit before you start taking photos or videos. |
| Some defective pixels cannot be permanently deleted. | The defective pixel is not recognised by the unit. | Switch the calibration to M mode and wait until the pixel is very clearly visible. Then carry out the error pixel correction ("Advanced settings" menu). Then switch back to A mode. |
| The LIEMKE app does not connect to the unit. | WiFi is not activated. Activate the WiFi of the unit in the menu. | |
| The mobile terminal is not connected to the KEILER-WiFi. | Connect your mobile end device to the WiFi of KEILER. | |
Battery
| Malfunction Possible reason | Remedy | |
| The battery charges very slowly or not at all. | Using a power supply unit with insufficient power. | Use a suitable power supply unit as specified in the operating instructions for the KEILER or CHARGER-K. |
| The battery is deeply discharged. | Charging takes a significantly longer time for deeply discharged batteries. |
