The CANtouch is a mobile measuring device for CAN-based bus systems

The further development of the CAN-Bus Tester 2 is battery-powered and equipped with a touch display. Its intuitive user interface allows extensive measurements to be taken in the shortest possible time. The results can be archived for documentation or later analysis and further processed on the PC.

The physical layer measurements have been extended to include the direct determination of potential differences between the participants (common mode/ground shift).

With the online trigger, you can monitor the bus for individual physical limits, determine problems over time and make errors visible in the oscillogram.

The protocol monitor is used for sending, receiving, decoding and recording messages.

  • Startup Operations - Ensure the functionality of your new bus system
  • Trouble Shooting - Bring your system in an error condition back to live quickly
  • Maintenance - Finish off pending service work efficient and exact
