AI Technical Summary
Traditional manual positioning or simple testing tools cannot meet the precise control requirements of the distance and angle between the test pen tip and the test electrode in the IEC 61557-17:2021 standard, resulting in low testing efficiency, insufficient accuracy of results, and inability to reliably verify whether the test pen conforms to international standards.
The testing device uses a three-axis displacement platform and a rotating stage for positioning. The position of the test pen and the test electrode is adjusted by the three-axis translation slide and the rotating stage to meet the distance and angle requirements of IEC 61557-17:2021 standard.
It achieves precise positioning between test pens of different sizes and metal conductors, improves testing efficiency and accuracy, simplifies testing operations, and is suitable for sensitivity testing of test pens of different sizes.
