4 Wire Mini Probe Set with dual gold-plated tips for the 620UK-V4, the 4-wire version of the 620UK
The 620UK-403V4 is a 4-wire Kelvin mini probe set with gold-plated dual tips, for the 4-wire 620UK-V4 (5-pin male circular connector), for small terminals where a clip will not fit.
Overview
The 620UK-403V4 is the 620UK-V4 probe for small terminals where a Kelvin clip will not fit; each mini probe makes both contacts in one touch. Leads are 48″ each (96″ total span), 1 lb per set, 5-pin male circular connector to dual gold-plated tips. Operating 0° to 50° C, storage -10° to 70° C. Evencat, sole distributor for AMPTEC Research in Taiwan, quotes accessories with delivery dates.

Compatibility and applications
Compatibility

620UK-V4 (4-wire version of the 620UK, also called V4). On this site: 620UK-V4. Ask Evencat if in doubt.
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.
