Frequently Asked Questions
Q: What does a four-terminal (Kelvin) resistor calibration board do?
A: A four-terminal resistor calibration board uses separate current-carrying and voltage-sensing connections to eliminate the effect of lead and contact resistance. This gives you a much more accurate reading when calibrating ohmmeters or verifying low-resistance measurements, making it the preferred method in professional lab and field settings.
Q: What resistance values are included on this calibration board?
A: This board supports six resistance values: 0.5, 1, 10, 20, 100, and 1000 mΩ. Each value is individually calibrated using a high-precision instrument, ensuring reliable and traceable measurement results across a wide range of testing scenarios.
Q: What is the difference between the Calibrated, Uncalibrated, and Blank versions?
A: The Calibrated version comes with factory-verified resistance values ready for immediate use. The Uncalibrated version is suitable for users who wish to perform their own in-house calibration. The Blank version provides a bare board platform for custom resistance configurations or prototype development.
Q: Is this calibration board compatible with all ohmmeters and resistance meters?
A: Yes — this board is designed as a universal calibration reference for standard ohmmeters, micro-ohmmeters, and insulation resistance meters that accept a four-terminal (Kelvin) connection. It is widely used in electrical testing labs, quality assurance workflows, and field maintenance applications.
