1.1 Product Overview

The BK Precision’s 2840 DC Resistance Meter can handle a broad range of resistances

measurements. Its maximum accuracy of 0.1% and its range, 1 mΩ to 20 kΩ are vividly

displayed on the color LCD touchscreen in 4½ digits. The 2840 is ideal for testing resistances

found in PCBs, conductors, relay contacts, interconnections, welding-holes as well as resistors

and bigger components. The statistical analysis function provides the average, maximum,

minimum, population standard deviation and sample standard deviation of the measured

datasets. The statistical analysis can also provide the Process Capability Index (Cp, Cpk) which

indicates the ability of a process to produce an output within the user’s specification limits.

Features:

 Measurement Range: 1 mΩ to 20 kΩ

 Minimum resolution: 1 μΩ

 Maximum accuracy: 0.1%

 Lower power measurement function: LPR

 Bin sorting comparator with up to 3 bins

 Process Capability Index (Cp)

 Standard USB and RS232C interface

 Intelligent detection for test state error

 Handler interface for on-line operation.

 4.3” LCD touchscreen, 480×272 resolution
