6.3 Technical alarm from the electrode contact
monitor
The electrode contact monitor reports an alarm when:
the electrodes have become detached,
the electrodes are too dry (e.g. the expiration date has been
exceeded or the electrodes have been used several times), giving
rise to too high a value of basal impedance.
When electrodes have become detached or when the electrical
resistance between the electrode and skin is too high, the respira-
tion and ECG signals are displayed as a zero line.
