Off-Set Kelvin Test Sockets
-
This is an innovative and robust contact technology for making Kelvin contact to 0.5mm pitch QFNs. The contact uses a tip that is angled to one side, matched to an orientation that's flat on the tip. Two such contacts placed in opposition will touch the pad within 0.125mm. And because the tip is offset, the probe diameter is a robust 0.39mm and the load board pad pitch remains 0.5mm.

4-Wire Resistance Measurement | Continuity & HiPot Cable & Wire Harness Testers
-
An add-on option for the CableEye HVX high voltage cable tester series that permits expanded testing for contact and wire resistance as low as 1 mΩ. After checking for opens, shorts, miswires, and resistance limits, the 4-wire Kelvin measurement applies a user-selectable test current from 10 mA to 1 A to determine connection resistance within 1 mΩ. The resistance profile of a model cable may be stored and used as a basis of comparison during later testing to reveal cold solder joints, faulty crimps, recessed pins, pin contact contamination, improper wire gauge, and stress-extruded wire.This option may be purchased with any new HVX tester, or added as an upgrade to any of your existing HVX testers.

Bridges
-
Equip your testing environment with portable, precise Wheatstone bridges and Kelvin double bridges from Transcat. The Wheatstone bridge is a device containing a divided bridge circuit for taking highly accurate resistance measurements. It captures the value of an unknown resistance, in comparison to known resistors within the circuit. Precision bridges provide exact resistance measurements in the miliohms (m_) to megohms (Mohm) range within their specified accuracies. We offer portable Kelvin double bridges, which are forms of the Wheatstone, designed to measure low resistance – with high accuracy. Transcat also stocks individual resistors, which provide resistance standards in low to high values. They operate in conjunction with potentiometers or bridges.
