the received signals are processed, displayed and presented in the different modes
after mathematical analysis. The initial data is stored on the hard disk and the exam
reports are generated and printed.
1.3. Connectors and Indicators
The front and side panels of the electronic unit are shown in Fig. 2, Fig. 3 and Fig. 4.
On the front panel of the electronic unit (Fig. 2) there are the touch-proof and DIN
connectors to attach the electrodes, the impedance button to switch to the
Impedance
measurement
mode and the LED indicator. The channels are marked with figures
“1” and “2”. The on/off indicator glows yellow when the unit is connected to PC and
it glows green during the signal recording.
The impedance indicators glow in the impedance measurement mode. You can switch
to this mode using the
Neuro-Audio.NET
program settings (see user manual)
or the
Impedance measurement
button. The colour of indicators means the quality
of the electrode placement. The green colour means the quality is high, yellow colour
– the quality is average and red colour – the quality is poor. The colours are specified
in the software settings.
