Field
Defense, aerospace and shipboard sites
Igniter circuits, electro-explosive devices and ground bonds differ in contact and span; probe type and lead length decide whether a reading repeats.
Lab
Calibration and QA laboratories
A 4-wire Kelvin connection to a resistance standard or the unit under test removes lead and contact resistance.
QA
Ordnance and pyrotechnics line QA
Batch sampling needs a fast, repeatable contact; keep several probe types on hand.
