Check that the electrical zero and the casing of the AMU130 are connectedtogether by a jumper (the non-floating mode is used). The casing socket is itselfconnected to the functional ground socket which is connected to the functionalground socket of the PGZ402 (via cable 4) and to the earth via the PGZ402 3-leadline cord.Cell (electrodes) connectionA 2-electrode (WE and REF) setting is used. The electrodes are connected to theAMU130. It means that the PGZ402 “Cell” button must not be pressed (“Cell” lampmust be off).POTENTIALCELLEXT. +0-1V WORKEXT.Working electrodeAMU130POWERONOFFSETCURRENTFILTERINT.RANGE REF.2nA200pAReference electrodeOFF±1V 20nA1ms 10Operation principleThe Vg potential scan defined in VoltaMaster 4 is output at the Vg OUT socket ofthe PGZ402. The AMU130 imposes Vg to the WE electrode versus the REF andmeasures the current (measurement range = 200 pA, 2 nA, 20 nA). The directpotential and I measured current are input at the E(X) IN and I(Y) IN sockets of thePGZ402.6.10.2 Configure Windows and VoltaMaster 4Configure Windows and VoltaMaster 4 as explained in section 3 “Getting started”.6.10.3 Set up <strong>your</strong> instrumentsSwitch on the PGZ402.Click the icon in the General bar or select the “File” menu then the “Newsequence” command.
