Low Voltage Cable Test Solution- WK260

The testers of the WK 260 family are designed to meet the needs for testing automotive har- nesses or functional elements. Most efficient test algorithms offer versatile programming and testing methods and result in highest test speed. New hardware solutions protect the testers against external voltages and allow at the same time to switch voltages up to 50 V for functional test applications.
