Save and export data with our app
June 2021 Update

Thanks to the latest update (June 2021), you can now export the data out of our system!

Before you begin

Please make sure your app is fully updated (from the App Store / Google Play, as any other app).

Please also make sure the device's firmware is up to date (please see the User manual).

Saving data

You can use our phone app to save measurements.

  1. Open our app (search "Matoha" on the App Store / Play Store if you don't have it installed yet).

  2. Create a Collection (My collections then a + button in the top right corner) or re-use an existing one.

  3. Connect to a machine (green button on the Home screen) and after you have successfully connected, please select Measurement Interface.

  4. Measure a sample - the result of the measurement should appear.

  5. Select the newly created collection and enter any other relevant information about the sample, such as the material or description. Press Save.

Exporting data

Now to the interesting bit. To start the export

  1. Go to My collections. You can use the icon in the top right corner while in the Measurement interface if you wish.

  2. Find the relevant collection and click on Data.

  3. A list of the saved measurements should appear. Press the Export dataset button at the bottom.

  4. Click on Generate link to create a unique link to this dataset. Keep this link safe - anyone with the link will be able to access your precious dataset! You can use the Copy link button to put the link into your clipboard.

Processing exported data

The data will be exported in the CSV format (comma separated values). The typical contents of an exported file are shown below:
