Project Overview
High Channel Count Resistance Measurement involves simultaneously measuring resistance across numerous channels — often dozens to hundreds — in systems like industrial automation, electronics testing, or material analysis. This approach is critical for efficiency in multi-sensor environments but introduces unique complexities.
KEC guides customers through every stage of high channel count resistance measurement projects, from understanding requirements and selecting the right hardware to developing custom software that automates testing, data collection, real-time monitoring, and report generation for efficient and accurate results.
What We Solved
The customer encountered several challenges when developing the test setup. KEC addressed each one systematically to deliver a reliable, scalable solution.
KEC evaluated multiple measurement approaches — two-wire vs. four-wire (Kelvin) methods — to identify the optimal technique for low-resistance, high-channel-count scenarios in an MRO environment.
KEC worked closely with the customer to define the appropriate instrumentation, switching hardware, and PXI platform to meet both accuracy and throughput requirements across all channels.
With dozens to hundreds of channels to manage, KEC developed a structured wiring and configuration strategy to minimise cross-talk, reduce setup errors, and ensure repeatable results across test runs.
The solution required tight integration of instruments, switching matrices, and custom software. KEC designed a unified test executive that coordinated all subsystems through clean software interfaces.
KEC optimised the test sequence to maximise throughput while maintaining measurement accuracy. The software architecture was designed to scale to additional channels with minimal rework.
KEC implemented shielding strategies, guard paths, and software-based noise rejection techniques to ensure low-resistance readings remained accurate even in an electrically noisy MRO workshop environment.
