The stimulator allows for diagnosising the status of the electrodes attached to it. A known stimulus is sent to each electrode and the voltage is recorded for the five data points during a stimulation, i.e. before the first phase, during the first phase, between the two phases, during the second phase and after the second phase. These voltage levels are then used along with the known stimulation to calculate the impedance of each electrode. A 1 kHz frequency is used for the stimulation.
