Configuring the material indicator LED (FabriTell)

Under the screen, the instrument has a colour LED which can be programmed to show particular colours for a particular material. For example, if you were sorting polyester for recycling and wanted to accept all samples with at least 70% poly, you could configure it to show green light (accept) for samples with >= 70% polyester and red (reject) otherwise.

By default, any material/blend scanned which does not obey any of the rules you apply, will make the LED turn red.

Step 1 - Connect to your device

Please connect to your FabriTell using our app.

Step 2 - Go to "Materials and colours"

Press "Materials and colours" to view and/or change the LED settings for your FabriTell.


Step 3 - Create or edit colour rules

You can create, edit or remove rules and can create as many rules as you want.  If there are samples which obey two or more rules, your FabriTell LED will display the colour according to the rule which is at the top of your list (i.e. it will follow the order of your rules).  

The different parts of a colour rule

The major component is the main material of your sample (i.e. has the greatest percentage out of all the components in your sample). For any rule, this can be changed to any of our supported materials, by tapping the arrow to display the drop-down menu - in the screenshot above we chose cotton.

You can then specify the percentage/s of that material you want associated with your chosen material. If you tap the drop-down menu, you will get the following symbols:

Based on your requirements, you can choose any of the above symbols from the drop-down menu and type in the numerical value you want.
You can then specify the minor component for your blend or use "any" if the identity of the second component doesn't matter.

Finally, you can select the colour you want your FabriTell LED to display when a sample which obeys your rule is scanned (green in the screenshot above).

Update February 2022: You can also choose "DON'T IDENTIFY" from the list of colours. This will disable the identification of a particular material 

Example: Adding a rule for the FabriTell LED to turn purple when you scan samples containing at least 70% polyester

Select "Add a rule"

Change the major component to polyester

Change the ">= 95" to ">= 70"

Leave the minor component as *any* since in this case, we are only concerned with the major component, polyester.

Change the colour to purple


Step 4 - Save your rules

Once you are finished with adding/changing your rules, tap on "Save settings". This will save your rules and you will be asked to restart your device.

Your device is now ready to use with your new rules!
