B&K Precision 2841 DC Resistance Meter

Overview

The B&K Precision 2841 is a benchtop DC resistance meter designed for high-precision measurement of low resistance values, including contact resistance of relays, switches, and PCB traces. With 0.01% basic accuracy and 0.1 µΩ resolution, it exceeds the capabilities of standard multimeters for applications requiring milliohm-range measurements.

Key Features

• Measurement range from 0.1 µΩ to 100 MΩ with 5-1/2 digit display
• Basic accuracy of 0.01% across measurement ranges
• 4.3-inch color touch screen with intuitive controls and keypad interface
• Low Power Resistance (LPR) mode to protect components under test
• Temperature compensation with correction (TC) and conversion (Δt) functions
• Offset Voltage Compensation (OVC) to minimize thermal EMF effects
• 4-wire Kelvin test leads included for accurate low-resistance measurement
• BIN comparator with up to 10 result bins for automated component sorting
• Handler interface for integration with automated test systems
• RS232, USB (USBTMC and virtual COM), and LAN connectivity
• Adjustable measurement speed for throughput optimization
• Cable error detection and screen capture to USB

Applications

• Relay and switch contact resistance measurement
• PCB trace and connection resistance verification
• Motor and transformer winding resistance testing
• Coil, actuator, and conductive material evaluation
• Component sorting and bin classification in production environments
