PATIENT CONNECTION

After the correct installation of the electromyograph and after verifying that it works properly, it is
possible to connect the sensors to patient in order to perform a biopotential recording. Follow the
instructions listed below:
For each input, select the suitable adapter for the measurement to perform and plug it into

on a point without any bioelectrical activity (e.g. the ankle or the wrist, FIG. 6).
REMARK: the lack of this connection prevents the correct acquisition of the EMG signal.
