Test Probe Selection
Test probes also have many different manufacturers, but all have similar constraints. When choosing a test probe receptacle, the most important decision is what tip to use.
The number of tips that are available can be overwhelming. From past experiences, we found that we typically only use a couple of different tips.
* Crown
* Spear
* Cup
* Cone
