Hioki RM3545A-2 Resistance Meter

Overview

The Hioki RM3545A-2 is a high-precision resistance meter designed for manufacturing quality control and automated testing. With support for up to two Z3003 multiplexer units, it can measure up to 20 channels using the 4-terminal method. It is ideal for measuring weld quality, contact resistance, and component resistance across multiple test points simultaneously.

Key Features

• 0.045% basic accuracy with 1 nΩ maximum resolution
• Measures from 1 nΩ to 1200 MΩ
• Maximum testing current of 1 A
• Offset Voltage Compensation (OVC) function corrects for electromagnetic force (EMF) effects
• Temperature correction function with ±0.5°C precision
• High path resistance tolerance for automatic test system integration
• Fast measurement speed (21 ms) for high-throughput testing
• LAN interface for easy data exchange with computers and PLCs
• Advanced contact-check and comparator functions
• Supports up to two optional Z3003 Multiplexer Units (sold separately)

Applications

• Multi-channel weld quality control in production lines
• Automated contact resistance testing of connectors and relays
• Motor and transformer winding resistance measurement
• Multi-point resistance testing in component manufacturing
• Integration into production line automated test systems
