An electrosurgical generator for supplying power, including an inverter for high voltage, which is led to an output to the connector of an electrosurgical instrument, a measurement system with at least one measurement monitor for a physical parameter at the output or at the electrosurgical instrument, and an operation controller which controls the inverter on the basis of at least one predefined operating sequence. The measurement monitor for the physical parameter is switchable between a plurality of different configurations which differ in the measurement range. The operation controller interacts with the measurement system so one of the different configurations of the measurement monitor is switched in each case, under control by the operating sequence. By switching the configuration, the suitable measurement range is always set during operation. Apparently contrariwise requirements in relation to a reliable measurement even at high amplitudes are linked with great measurement accuracy even at low amplitudes.
