Figure 6.7

The

Signal display

window, in case when the impedance measurement is

selected. The indication of the impedance values are presented in the left part of the

Signal display

window (22). The red line denotes the most recent samples (23).

6.5 Streaming signals with 500 Hz sampling frequency and with the
impedance measurements switched off

Upon  mounting  the  cap  and  ensuring  the  proper  electrode  contacts,  it  is
advisable  to  switch  off  continuous  impedance  measurement  before
proceeding to data visualization and acquisition, because this will reduce the
high  frequency  noise  components.  If  the  box

No impedance measurement

(number 13 in Figure 6.4) is selected and the sampling frequency is set to 500
Hz (number 14 in Figure 6.4), the streamer main window looks like the one
depicted in Figure 6.8. Two main differences between the cases

measure

impedance

and

No impedance measurement

is that when impedance

measurement is not selected, the electrode layout does not have the color
codes (17) and it is not possible to observe impedance values, as it can be
seen from Figure 6.8.
