Using impedance measurement
4.5
The impedance measurement of the Refa is controlled by the commands from the
application software. Refer to instructions for use of the application software to use
impedance mode on the Refa.
The device requires the following to be able to measure the impedance correctly:
-
At least one odd and one even channel above channel number 4 must be
connected
-
Connected Patient Ground electrode.
-
The system must be set to impedance mode.
Until all these requirements are fulfilled, impedance LEDs will blink to indicate that
impedances cannot be determined properly.
Please follow the instructions for use for the TMSi Polybench Quick Recording
Application. For other application software, refer to the user manual of that
software.
