Hioki RM 3542A resistance meter

The Hioki high-speed electrical resistance tester RM3542A provides resistance measurement of components including ferrite bead inductors. Low-impact contacts limit inductive limitation inrush current, while low applied voltage (5 V) permits no-stress testing of small components.

The isolated four-terminal testing mode allows resistance measurement to 100 MW with minimal interference from environmental electromagnetic noise. Unreliable results are eliminated by contact checking modes including Always-On Contact checking (contact checking before and after contact bounce) and Contact Improver Function (improved penetration prevents oxidation layers from interfering with the accuracy of resistance measurement).

The Offset Voltage Compensation feature eliminates the interference of thermal EMF with the accuracy of measurements. Automatic power line frequency sensing provides for in-sync resistance measurement. Measured values are automatically subjected to statistical analysis including mean, minimum, maximum and standard deviation, as well as process indicators such as dispersion and bias factors.
