HD-PA3 SeriesThis range of probes can be used for load and functional testing of power components such as semiconductors, solenoids, loaded PCBs, bus-bars, wound components and batteries. They share identical dimensions and will readily intermix with the PA3, PA4, PA5, PA6 and PA7 general purpose probes. In particular, the HD-PA4 series is physically interchangeable with the PA4 series used in standard ATE test fixtures.
