PARAMETER
This menu offers the selection of stimulation waveform modes and the associated
parameters like current, duration etc..
The chosen parameters can be saved into configurations (setting A - D) by pushing button 1
and 3 simultaneously. Stimulation parameters, which are not saved in a configuration, can
not be recalled on the next start-up.
To modify the stimulation waveform mode please follow these instructions:
- Press button 2 or 4 to select main menu PARAMETER.
- Move the cursor to line 2 on the display by pressing button 3.
- Switch to desired stimulation waveform mode by pressing button 2 or 4 several times.
To modify the parameters current, duration etc. please follow these instructions:
- After you have switched to the desired stimulation waveform mode move the cursor to
line 3 by pressing button 3.
- Press button 2 or 4 to select the desired parameter.
- Move the cursor to line 4 by pressing button 3.
- Pressing button 2 und 4 you can set the parameter. Press button 1 to confirm and save
the value.
tDCS
Using the stimulation waveform mode tDCS a transcranial direct current stimulation can be
applied.
A current of value [current] µ A will last for [duration] seconds.
To avoid painful current steps the user can define controlled rising and falling of the DC by
adjusting
[fade in] and [fade out] values (Figure 21). These fade in and fade out periods are
both additional to the stimulation's [duration] . The total stimulation time will therefore be
calculated as follows:
