5.1.4 UseThe PGZ and PST potentiostats are fully controlled from a personal computer withthe VoltaMaster 4 Electrochemical Software. Section 4 “VoltaMaster 4” of thisUser’s Manual describes how to create and run an experiment.The use of additional equipment (rotating disc electrode, rotating ring and discelectrode, mercury drop electrode, external signal generator, another potentiostat,high voltage booster oscilloscope, rotating disc stand) are described in Section 6.Warning!Never connect, disconnect or handle an electrode when the “CELL” button of thePGZ or PST is lit. Press the “CELL” button before doing this operation.1. Using an oscilloscopeAn oscilloscope can be connected to one of the two “E OUT” or “I OUT” socketson the front panel of the PGZ potentiostat. Make sure you connect the electricalzero of the oscilloscope to one of the two socket shieldings and the oscilloscopeinput signal (live point) to the central contact of the PGZ sockets. If the conditionexplained above is fulfilled, the E (measured potential) and I (measured current)signals can be read on the oscilloscope screen. A 2-channel oscilloscope can alsobe used to display the E and I signals simultaneously.2.
