8. ARE YOU HAVING DIFFICULTIES?
8.1. The IR image I obtain is solid-colour
8.1.1. The palette of colours is frozen
Make sure that the low and high temperature limits of your palette are consistent with the temperature range of your scene. To check
this, unlock the palette (see § 2.7
. Freezing the colours representing the temperatures ).
8.1.2. Inconsistent "user" influencing parameters
The entry of an incorrect emissivity value can lead to measurement errors of this type. Check your influencing parameters in the
"Main/Target" menu. If there is any doubt, restore the "default" influencing parameters.
8.2. The contrast of my IR image is wrong

Make sure that isothermal measurement is not activated.

If the palette is frozen, make sure that the low and high temperature limits of your palette are consistent with the
temperature range of your scene.
If there is any doubt, unlock the palette (see § 2.7.
Freezing the colours representing the temperatures ).

The temperature range of the image is very large (hot and cold points very far apart), so the linear distribution of the
colours between the minimum and maximum temperatures is in larger steps, impairing the contrast of the image.
Several solutions are possible:
-either freeze the palette and set the limits according to the range of temperatures that interest you,
-or arrange to keep the hot or cold point which does not interest you outside the field of view of the camera, so as
to reduce the temperature range of the image.
8.3. I am unable to save the current image

Make sure that the micro SD card is correctly inserted in its slot and displayed as being present in the status bar of
the main screen (see § 1.4.1.1.
Status bar ).

Make sure that your micro SD card is not full (with FAT16 formatting, watch out for the number of entries in the root;
see § 1.5.7.
Changing the image backup location ).

Make sure that your micro SD card is not corrupted and that you can read/modify its content on a PC via the USB
cable or a card reader.
8.4. The file manager takes a very long time to respond
The access time to the SD is relatively long. To make it shorter, favour the creation of new directories to store your images and
limit the number of files per directory. We suggest regularly uploading your images to a host PC via the USB cable or a card
reader.
8.5. I cannot connect my headset

Make sure that your headset is correctly powered and that it is not automatically connected to another instrument
with which you have already paired it.

Switch off your headset and repeat the operation as described in § 6.2.2. Connecting a headset .

If the problem persists, deactivate the Bluetooth function on the camera (see § 6.1. Activating/deactivating the
Bluetooth function ), re-activate it and then make another attempt to connect.
8.6. I cannot connect my Bluetooth peripheral

Make sure that your peripheral is correctly powered, configured in Bluetooth mode, and not already used by another
instrument.

Switch off your peripheral and repeat the operation described in § 6.3.4. Connecting a Bluetooth measurement
peripheral.

If the problem persists, deactivate the Bluetooth function on the camera (see § 6.1. Activating/deactivating the
Bluetooth function ), re-activate it, then make another attempt to connect.
