High accuracy and resolution measurements in the milliohm range
B&K's 2841 DC resistance meter is ideally suited for measuring contact resistance of relays, switches, and PCB traces, typically outside the resistance range of multimeters. The 2841 is equipped with an intuitive front panel complete with a keypad and a vivid 4.3-inch color touch screen. Additionally, it supports fast cycle times for production automation and includes a BIN comparator function.

Intuitive user interface
The touch screen and keys both provide a convenient interface for setting parameters quickly and precisely. Both models also support one touch zoom to enhance the readability of displayed measurements.

Extended range, accuracy, temperature measurement and functions
The 2841 allows measurement of 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.

LPR (Lower Power Resistance) measurement
The 2841 features 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 2841 to evaluate a large quantity of components and be integrated into an automated test system.

Temperature measurement with correction
The 2841 includes two temperature compensation functions: correction (TC) and conversion (Δt). The TC function corrects for ambient temperature changes that cause different resistance measurements of the same component. The temperature conversion (Δt) function can be used to evaluate a coil’s resistance before and after operation to calculate a temperature change. These additional features make the 2841 ideal for evaluating coils, motor windings, transformers, actuators and conductive materials.

Offset voltage compensation (OVC)
OVC switches the polarity and averages the forward and reverse polarity readings. This enables accurate measurements by minimizing the adverse effects of thermal EMFs or small biases in a circuit (e.g., from a capacitor's dielectric absorption when measuring a PCB trace).

Kelvin Test Leads included Measure the resistance of motor and transformer windings, relay and switch contacts, and other conductive materials and components.

Included with 2841: AC power cord, user's manual, TLDK1 kelvin test leads, TPTC2 temperature probe, and test report and certificate of calibration.
