6. Operation

  • Remote Control:

The remote connectors of RRDE-3A control rotation and gas purge functions by an external unit. The RRDE-3A is designed to be controlled by the appropriate commands from the potentiostats. When it does not use, make sure that power is turn out. These functions are activated either by a TTL signal or from any other controllers.

Each connector is connected properly with each electrode, and make sure that its electrical connection is confirmed.
