Data Transfer

Open the cover on the micro USB port (3). Connect the micro USB port (4) of the measuring tool to your computer via the micro USB cable (24) provided.

Now press the on/off button (9) to switch on the measuring tool.

Open the file browser on your computer and select the GTC_400C drive. The saved files can be copied from the internal memory of the measuring tool, moved to your computer or deleted.

As soon as you have finished the required operation, disconnect the drive from the computer following the standard procedure and then use the on/off button (9) to switch the measuring tool off again.

Caution: Always disconnect the drive from your operating system first (eject drive), as failure to do so may damage the internal memory of the measuring tool.

Remove the micro USB cable during the measurement operation and close the cover (3).

Always keep the flap of the USB port closed so that dust and splashes cannot enter the housing.

Note: Use USB to connect the measuring tool to a computer only. The measuring tool may be damaged if connected to other devices.

You can post-edit the saved thermal images on your computer if it uses a Windows operating system. To do so, download the GTC Transfer software from the product page for the measuring tool at www.bosch-professional.com/thermal.

The measuring tool is equipped with a Wi‑Fi® interface which enables the saved images taken by your measuring tool to be wirelessly transmitted to a mobile device.

Special Bosch applications (apps) are available for this use. They can be downloaded in the store corresponding to your device:

In addition to the wireless data transfer of your images, the Bosch applications make it possible for you to use an extended range of functions and make it easier to post-edit and forward measured data (e.g. via e-mail). Information about system requirements for a Wi‑Fi® connection can be found on the Bosch website at www.bosch-professional.com/thermal.

To activate or deactivate the Wi‑Fi® connection on the measuring tool, call up the main menu, use the buttons to select <WiFi> and activate or deactivate it. The indicator (d) appears in the display when the Wi‑Fi® is activated. Ensure that the Wi‑Fi® interface is activated on your mobile device.

The connection between the mobile device and the measuring tool can be established after the Bosch application has been started (if the Wi‑Fi® modules are activated). To do this, follow the instructions in the application (app).
