Compatible instruments and applications
FIELD
Defense, aerospace and shipboard work
Firing circuits, electro-explosive devices and ground bonds are measured on site, where contact shapes and distances vary. The right tip and lead length are what make readings repeat.
LAB
Calibration and QA labs
A 4-wire Kelvin connection to a resistance standard or the device under test removes lead and contact resistance from the reading.
QA
Ordnance and pyrotechnics production QA
Batch sampling needs fast, repeatable contact. Keep several lead sets with different tips on hand and swap to match the terminal.
