8. TROUBLESHOOTING
8.1. IR Image is a Single Solid Color
8.1.1. Color Palette Frozen
Ensure the low and high temperature limits of your palette are consistent with the temperature range in your
environment. To check this, unlock the palette (see
§ 2.2 ).
8.1.2. Inconsistent "User" Influencing Parameters
An incorrect emissivity value can result in measurement errors. Check the influencing parameters in the Target
menu (see
§ 3.2 ). If you question any of the settings, restore the default parameters (see § 3.2.1 ).
8.2. Contrast of IR Image is Incorrect

Ensure that Isotherm measurement is not activated (see § 2.1.6 ).

If the palette is frozen, ensure that the low and high temperature limits are consistent with the
temperature range in your environment. To check this, unlock the palette (see
§ 2.2 ).

If the temperature range of the image is very large (hot and cold points are very far apart), the linear
distribution of the colors between the minimum and maximum temperatures will be in large steps. This
impairs the image contrast. To address this, do one of the following:
-
Freeze the palette and set the limits to the temperature range of highest interest.
- Keep the hot or cold point of lower interest outside the field of view of the camera, to reduce the
temperature range of the image.
8.3. Unable to Save Displayed Image

Ensure that the micro SD card is correctly inserted in its slot, and that the status bar indicates the card is
present (see
§ 1.4.1.1 ).

Check the micro SD card to see if it is full (with FAT16 formatting, check the number of entries in the root;
see
§ 1.5.7 ).

Ensure the micro SD card is not corrupted and that you can read/modify its content on a computer via the
USB cable or a card reader (see
§ 4.6 ).
8.4. Slow Opening of Files
The access time to the micro SD card is relatively long. To shorten it, you can create new directories to store
images and limit the number of files per directory. We suggest regularly uploading your images to a host
computer via the USB cable or a card reader.
8.5. Headset Cannot Connect to Camera

Ensure the headset is powered ON and that it is not connected to another instrument with which you
have already paired it.

Switch the headset OFF and repeat the connection procedure described in § 6.2.1 .

If the problem persists, deactivate Bluetooth on the camera (see § 6.1.2 ), re-activate it, and then attempt
to connect.
8.6. Bluetooth Device Cannot Connect to Camera

Ensure the device is powered ON with Bluetooth activated, and not already used by another instrument.

Turn OFF the device and repeat the connection procedure (see § 6.3 ).

If the problem persists, deactivate the Bluetooth function on the camera (see § 6.1.2 ), re-activate it, and
then attempt to connect.
