Obtain Accurate Milliohm Measurements With 2840 & 2841 Resistance Meters

Oct. 13, 2017
B&K Precision offers a new line of resistance meters that accurately record milliohm measurements.

The first series of DC resistance meters, models 2840 and 2841, are designed to accurately measure resistance in the milliohm range. Both meters are ideally suited for measuring the contact resistance of relays, switches, and PCB traces with greater accuracy and resolution than typical multimeters.

Bench DC resistance meters are used in R&D and on production lines where measurement accuracy and resolution in the milliohm range are required. Both meters feature low power resistance testing (LPR) modes and variable measurement speeds that are suited for a wide range of applications. The handler interface with high-speed measurement capabilities enables the 2840 Series to evaluate a large number of components and be integrated into an automated test system.

Each model features a touch screen, one-touch zoom, and pass/fail binning for ease of use when evaluating components. The front panel provides intuitive menu navigation and a 4-terminal input for accurate Kelvin measurements. The DC resistance meters also feature discrete and auto-ranging measurements for comparator, binning, and statistical displays.

The 2841 model adds extended range, accuracy, temperature measurement, and functions. Measure low resistivity materials with offset voltage compensation to reduce the influence of thermal EMF. Cable error detection displays a message when one of the terminals is open, which helps identify defective test leads or poor contact that can cause unreliable measurements.

Control the series with SCPI and instrument-specific commands over standard USB and RS232 interfaces for remote PC connectivity. The 2841 extends the remote control capabilities with a LAN interface and features a built-in webserver.

Features:

  • 4.3-in. color touchscreen
  • 4-wire terminal Kelvin test leads included
  • Low power resistance mode to protect DUT
  • Fast measurement speed up to 20 ms/reading to increase manufacturing throughput
  • Bin-sorting with statistical measurement
  • Screen capture to USB drive
  • Standard RS232, USB (USBTMC and virtual COM), and LAN (2841 only) interfaces
