Hioki RM3543 Resistance HiTester

Description

The Hioki RM3543 Resistance HiTester is a high-precision DC resistance meter designed for measuring super-low resistance values, particularly for components like shunt resistors and those in EV development. It is well-suited for automated production lines due to its high speed, repeatability, and robust features.

Key Features

• High-resolution measurement: Offers a high resolution of 0.01 μΩ in the 10 mΩ range, allowing for precise measurements of ultra-low resistance.
• Shunt resistor measurement: Can measure 0.1 mΩ shunt resistors with a high accuracy of ±0.16% when using the averaging function, which is useful for testing in automotive applications.
• Offset voltage correction (OVC): Applies current in both positive and negative directions to cancel out the effects of thermoelectromotive force, a potential difference that can occur at the junction of different metals and cause measurement instability.
• Contact improvement: Provides a function to suppress rush current and eliminate oxide films or dirt, ensuring better contact between probes and specimens for more reliable measurements.
• Pulse application function: Applies current only during the measurement cycle to minimize heat generation in the sample, which helps reduce resistance value fluctuations.
• Noise immunity: Complies with international electromagnetic compatibility (EMC) standards to minimize the effect of electromagnetic interference from nearby production equipment.
• Interfaces: The RM3543 comes with standard External I/O, RS-232C, and Printer interfaces. The RM3543-01 model includes an additional GP-IB interface for automated control.
• Probe short-detection: Checks for short circuits between the POT and CUR measurement probes to ensure the reliability of the four-terminal measurement.
• Scaling function: Allows for correction of resistance values to account for different measurement conditions, such as on-board versus off-board testing.
