[Test-Equipment] Probing terminal strips

[Tod - MN]

AT the hardware store you can buy a "widget" that has a hole in the middle
with slight grooves on the outside.

When you poke a screwdriver through the hole in the 'widget' it comes back
out magnetized and can be used for picking up screws, nuts and similar
ferrous based things. When you slide the magnetized screwdriver along one of
the grooves from handle to tip, the screwdriver is de-magnetized again.

I bet you could figure out how to  fabricate a 'magnetized' probe for your
application if you had one of these 'widgets'.

Tod, KØTO
