DC Bench Resistance Meter

High accuracy and resolution measurements in the milliohm range

SKU BK2840 Series Category

Call for price


The BK2840 Series DC resistance meters feature high accuracy and resolution measurements in the milliohm range. Both meters are ideally suited for measuring contact resistance of relays, switches, and PCB traces, typically outside the resistance range of multimeters. The vivid 4.3-inch TFT LCD colour touch screen and keypad provide intuitive operation.

Both models 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 enable the BK2840 Series to evaluate a large quantity of components and be integrated into an automated test system.

The BK2841 model adds extended range, accuracy, temperature measurement and functions. It also allows you to measure low resistivity materials with offset voltage compensation to reduce the influence of thermal EMF. Another benefit is the cable error detection facility. This displays a message when one of the terminals is open, which helps identify defective test leads or poor contact that can cause unreliable measurements.

The BK2841 includes two temperature compensation functions: correction (TC) and conversion (∆t). The TC function corrects for ambient temperature changes that cause different resistance measurements of the same component. The temperature conversion (∆t) function can be used to evaluate a coil’s resistance before and after
operation to calculate a temperature change.

These additional features make the BK2841 ideal for evaluating coils, motor windings, transformers, actuators and conductive materials.
