Quickly sort components using the 3 bins of the 2840. The results can be displayed on the screen or output via the handler interface. High and low limits can be set up in absolute or tolerance mode. |
High accuracy and resolution measurements in the milliohm range
B&K's 2840 DC resistance meter is ideally suited for measuring contact resistance of relays, switches, and PCB traces, typically outside the resistance range of multimeters. The 2840 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.

LPR (Lower Power Resistance) measurement
The 2840 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 2840 to evaluate a large quantity of components and be integrated into an automated test system.
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).
