Abstract
In a device for monitoring measurement electrodes, attached to a patient in order to pick up physiological measurement signals, and a neutral electrode and associated leads at the same time as physiological measurement signals are picked up, each measurement electrode is connected to an input terminal on its associated measurement amplifier. A test signal generator is arranged to generate a pure AC signal, without any direct current component, across the neutral electrode attached to a patient during the pickup of measurement signals.
