7. Check that the waveforms are acquired correctly and that the amplitude of each
waveform is proper.
Click the EEG Signal button on the tool bar and check that all waveforms are
measured correctly (i.e. there is no waveform distortion and the amplitude of
each waveform is proper). To change the sensitivity, select a channel number,
then click the Sens button on the amp bar or Sensitivity dialog box or use the
pattern table.
On the screen:
1) Move the mouse pointer to the Impedance Check button on the tool
bar.
2) Press and hold the left mouse button for about two seconds to start the
skin-electrode impedance check. The Impedance Check dialog box opens
on the screen. The currently selected montage is displayed on the dialog
box.
The impedance check result is displayed on the screen with measured
impedance and color. If an electrode’s impedance exceeds the preset value
(threshold) on the System program, it is highlighted on the Impedance
Check dialog box.
3) Click the OK button to close the Impedance Check dialog box.
