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.
The CANtouch supports four bus systems in physical layer measurements : CAN, CANopen, DeviceNet and SAE J1939.
It can also be used for measurement in other bus systems based on the CAN standard. These include Isobus, NMEA 2000 and SafetyBus P, but also Energybus, CANaerospace and ARINC825. Niche bus systems also include MilCAN and CANopen Lift.
