Data Sheet DC Resistance Meters 2840 Series Touch screen to zoom, select, and enter values USB LAN* RS232 functions: correction (TC) and conversion (t). The 2840 Series DC resistance meters feature The TC function corrects for ambient temperature high accuracy and resolution measurements in the changes that cause different resistance milliohm range. Both meters are ideally suited for Features & Benefits measurements of the same component. The measuring contact resistance of relays, switches, n 4.3-inch color touch screen temperature conversion (t) function can be used and PCB traces, typically outside the resistance n 4-wire Kelvin test leads included to evaluate a coils resistance before and after range of multimeters. The vivid 4.3-inch TFT LCD n Temperature measurement with correction* operation to calculate a temperature change. color touch screen and keypad provide intuitive n Low power resistance mode to protect DUT These additional features make the 2841 ideal for operation. evaluating coils, motor windings, transformers, n Manual or auto ranging actuators and conductive materials. The 2841 model adds extended range, accuracy, n Adjustable measurement speed for fast readout temperature measurement and functions. Measure or better accuracy Both meters feature low power resistance testing low resistivity materials with offset voltage n Fast measurement speed up to 20 ms/reading (LPR) modes and variable measurement speeds compensation to reduce the influence of thermal to increase manufacturing throughput that are suited for a wide range of applications.
