The "Filter Amplifier Control" dialog.
Selecting the "Filter Amplifier Gain"
You can choose among four gain settings from factor 100 to 1000.
In the "Filter Amplifier Gain" window, please click one of the radio buttons to select the gain
factor.
Selecting the "Measure / Stimulate" mode
In the "Measure / Stimulate" window you can toggle between stimulation and recording mode
for each of the eight channels separately.
Please click the respective radio buttons for the channels in use.
Important: A ground electrode connected to the ground of the STG3008-FA amplifier is required
for proper use. The ground of the stimulation is connected to the ground of the amplifier inside
the device. The amplifier ground is the reference point for both stimulation and recording.
Without an appropriate grounding, the behavior of the system becomes unpredictable. The
ground electrode should have a large surface area, for example, a liquid gel adhesive electrode.
It is best positioned in an electrically inactive region (not near muscle, nor heart), but as near to
the recording site as possible, for example, at the belly.
