Message
Location Explanation What to do
●
AEP stimulation on
●
param.
The measurement is being
performed and clicks are being
delivered to the headphones.
●
Wait until the stimulation is
completed.
●
Artifacts
●
param.
Electrodes are poorly connected,
or electrical interference is
coupling to electrode cables.
●
Check the electrodes and
their impedances.
●
Remove the sources of noise,
if necessary.
●
Big contact difference
●
param.
The electrode impedance check
fails.
●
Check the contact quality
from the active and
baseline (+ and -) electrodes
establishment to ensure
measurement from the same
noise signal.
●
Perform a new electrode
impedance check.
●
Check GND electrode
●
param.
The ground electrode
impedance is over 5 kOhm.
●
Check the contact quality
from the ground electrode
establishment.
●
If necessary, change the
electrode.
●
Perform a new electrode
impedance check.
●
Checking electrodes
●
param.
Electrode impedance is being
measured and EEG analysis is
stopped for a few seconds.
●
Wait until the electrode
impedance check is
completed.
●
EEG leads off
●
Leads off
●
al. area
●
param.
Leads are not connected.
●
Reconnect the disconnected
headbox leads.
●
EEG measurement off
●
param.
The measurement has been
stopped.
●
Restart the measurement if
required.
●
EEG measurement
removed
●
al. area Acquisition module has been
removed.
●
Connect the module if
you want to restart the
measurement.
●
Electrodes OK
●
param.
Electrode impedance is below 5
kOhm.
●
You can continue the
measurement.
