3- electrode system:

Greed & white alligators (WE+SENSE) connect together to working electrode (WE);

Red alligator (CE) connects to counter electrode

Yellow alligator (RE) connects to reference electrode

Most of the time the 2 black wires are not used. Black (GND) connects to galvanic electrode WEⅡ in electrochemical noise experiment. If you use a Faraday cage, black GND & Shield should jointly connect to the cage.

2- electrodes system:

The green & white alligators (WE+SENSE) jointly connect to WE or Anode;

Red & yellow alligators jointly connect to counter electrode or Cathode.

Please pay attention that when you use the CS910 Pt counter electrode, the CE aligator should connect both the red and blue wire.
