Preparing for ECG Recording: Electrode Application
„
Apply the electrodes according to instructions.
„
Do not apply the electrodes on top of clothing.
„
Use a contact agent (e.g. moistened electrode paper, electrode cream,
spray, etc.).
„
Wait approximately 10 seconds before initiating a recording. After
the 10-second period, the automatic functions are enabled and the
polarization voltages have stabilized, provided the electrodes are
properly applied. In case of improper electrode application, an error
message will appear on the display (RL, LL, LA, LL, V1 to V6).
„
If required, the ADS (cubic spline) and the filters (20/40 Hz, 50 Hz)
can be disabled to verify the "raw" ECG signal.
