The CAN Bus Tester is a universal tool for installation, commissioning and maintenance of CAN, CANopen and DeviceNet devices and networks.

By means of an electrical line analysis the CAN Bus Tester enables not only experts to quickly identify and localize bus problems. The tester, which is supplied in a handy service case, helps especially electricians, service technicians and operating staff with unsophisticated system diagnosis. By an analysis of CAN messages of low signal quality, typical errors such as the use of wrong cable types, improper cable installation or faulty driver function of individual CAN stations are quickly detected. The CAN Bus Tester consists of easy-to-handle measurement hardware which is connected to the PC by USB and diagnostic software offering comprehensive analysis and display of measurement results.
