A manual electrode check can be carried out at any time independent of the automatic
electrode checks.
Adherence to the limit values for the impedances is required in order to ensure proper
operation of the device. Furthermore, it is important to make sure that the impedance
values of the individual electrodes are as uniform as possible. Whenever the limit
values for the impedances or the differences between the impedances are exceeded,
analysis of the incoming EEG data is impossible, and a corresponding message is
shown.
