Heavy Duty Kelvin Clamp Jaw Lead Set (10 ft) for the AMPTEC 630 / 640 / 641 Series ruggedized units
630-408J is a 10 ft heavy-duty Kelvin lead set with two jaw clamps and a Trident connector on the instrument end. It fits every AMPTEC 630 / 640 / 641 Series unit and any tester with Trident terminals.
Overview
For thick conductors, lugs and ground studs where you want to clamp on, step back and read hands-free. Leads are 10′ per lead (20′ total span); the set weighs 2.5 lb. Operating 0° to 50° C, storage -10° to 70° C. Other lengths and tip types are built to order. Evencat is the sole distributor for AMPTEC Research in Taiwan and quotes accessories together with the instruments.

Features
Heavy-duty jaw clamps
Wide jaws grip thick conductors, lugs and ground studs and stay put for a hands-free reading.
10 ft leads
10 ft per lead, 20 ft total span, for structures where the test points sit far apart.
4-wire Kelvin connection
Separate current and sense paths take lead and contact resistance out of low-resistance readings.
Trident connector
Matches the AMPTEC 630 / 640 / 641 ruggedized units and any tester with Trident terminals.
Custom lengths and tip types
AMPTEC builds other lengths and tips to order. Describe the application and we confirm spec and lead time with the factory.
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.
