RM3545A Kelvin resistance comparison

HIOKI · Engineering measurement and characterization

Purpose: RDL contact or wiring resistance needs comparison under controlled connection and temperature conditions.
Technical approach: RM3545A uses DC four-terminal measurement with thermal-EMF offset compensation, contact checks and reference-temperature correction.
Scope of use: Use accessible Kelvin terminals, matching range, current, probes and fixtures to the structure. Multichannel capability is model/option dependent.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Four terminals do not isolate every on-sample conductor contribution. One reading cannot locate a particular via; resolution is not total uncertainty.
What to prepare
BLNKK suggests Kelvin/reference structures, expected resistance, permitted current and temperature conditions to assess self-heating and fixture repeatability.
Confirm with the supplier
Confirm current/low-power settings, probes, fixtures, compensation, uncertainty and any switching options.
Public evidence: The product page and brochure, current as of July 2025, explain methods, current settings and conditions for representative accuracy.
