This has been incorporated into a mobile rack to use the testing system quickly and flexibly. Our multifunction tester KT 3881F can test virtually all national and international standards. Among others, a leakage current test was also included to ensure this. A connector panel with different sockets and test sockets meets the requirement of connecting different products. Testing with high voltage test probes is also an option. The testing system is equipped with WLAN to allow complete documentation of the test results. All test results are stored with the associated serial number in PDF format on the server. Here, the test programs, which are then installed on the testing system are managed.
