Abstract: An electrical measurement device is described, with a measurement input, an integrated sensor, a measurement and evaluation circuit, and a measured value display, and several measured value outputs. The electrical measurement device enables not only one measured value or several measured values to be determined, but makes it possible to display and process the determined measured values depending on other values such as comparison values and setpoints. An influencing input acts on the measurement and evaluation circuit and is the connecting point for the electrical measurement device to which or via which an influencing value can be applied or input. Therefore, a value with which the measured value can be influenced in the broadest sense is applied.
