CAN-Bus Tester 2

SKU #: PR-22517-10

The CAN-Bus Tester 2 is a tool for diagnosing and fixing problems in CAN bus systems. It checks the signal quality on the bus, which helps to find and solve common errors. It also tests the wiring and compares the measurements over time to prevent failures.

  • Bus systems:
  • Baud rates (5 kbit/s ... 1 Mbit/s)
  • Measuring of the signal conditions:
    • General quality level (0 ... 100 %)
    • Disturbance-free voltage range, rising and falling edges
  • Continuous monitoring
    • Bus status, bus traffic load, error frame counter
  • User-friendly protocol monitor (CAN, CANopen)
  • Online trigger (real-time monitoring of the bus for logical and physical errors)
  • Testing of cables (Short-circuits, interruptions, loop resistances, cable length)
  • Straightforward application software:
    • Management of measurements (measurement types, measuring points, measuring times)
    • Comprehensive test record, broad variety of export functions

Fields of Application:

  • Commissioning of CAN bus plants
  • Wiring test, module check
  • Service/maintenance of CAN bus plants
  • Troubleshooting and analysis of the bus characteristics
  • Development of CAN modules
  • Final production testing
