the PGP201 internal signal generator. In the “START” mode, pressing the “START/STOP” key stops the scan in progress and no current will pass through the cell.Refer to the PGP201 User’s Manual for more information.“E OUT” socket (6)This BNC type socket repeats the potential of the WORK measured versus theREF. This socket has an output impedance of 10 kOhm.“I OUT” socket (7)This BNC type socket repeats a linear potential signal ±1 V repeating the currentmeasured at the electrodes: ±1 V corresponds to the selected current range value.This socket has an output impedance of 10 kOhm.“Vg OUT” socket (8)This BNC type socket outputs the applied potential. The socket has an outputimpedance of 10 kOhm.“Vs OUT” socket (9)This BNC type socket repeats one tenth of the PGP201 output voltage (i.e. onetenth of the AUX. potential set versus the WORK. The WORK potential correspondsto the electrical zero of the PGP201 in “OPERATION” mode. This socket has anoutput impedance of 10 kOhm.Important:The (6), (7), (8) and (9) sockets have a 10 kOhm output impedance. The mVmeter or the recorder to be connected to these sockets must be fitted with highimpedance inputs (higher than 1 MOhm) in order to get accurate potential readings(max.: ±1 %).“Vg IN” socket (10)This BNC type socket is to be connected to an external signal generator. Thissocket has an input impedance of 20 kOhm.. central contact: input of the generator signal. shielding: connected to the electrical zero of the instrument136VoltaLab 21/06/10/40/50/80Section 5, Chapter 2: The PGP201 Potentiostat/Galvanostat
