Visual IFVA virtual front panel is also available by selecting the “Settings - Visual IFV”command. This tool can be used to set a potential and measure the current just asif <strong>your</strong> instrument was an analog instrument. No record of the data is provided.Consult the Help file, keyword index:Visual IFV.4.3.7 Pot. CV 4 limitsThe Pot. CV 4 limits method is the only VoltaMaster 4 method that allows to runcyclic voltammetries starting and ending at a same potential value such as theOpen circuit potential (OCP) for example. The scan rate can be programmed upto 500 mV/s. Auto ranging for current measurement is available depending on thescan rate. Method available with VoltaLab 10, VoltaLab 06, VoltaLab 40, VoltaLab50 and VoltaLab 80.Consult the Help file, keyword indexes:Pot CV 4 limits - Method editing, Pot CV 4 limits - Measurements and curvefiles.4.3.8 Pot. Linear VThe Pot. Linear V is a linear voltammetry between two applied potential set points.The potential is swept at a given rate and the current is measured. The scan ratecan be programmed up to 15 000 mV/s (10 mV/s with a VoltaLab 21). The stepamplitude and step duration are determined from the potential limits and the scanrate entered. Autoranging for current measurement is available irrespective ofthe selected scan rate. Points are saved at a selectable rate (as many as 1 in 32points).Consult the Help file, keyword indexes:Pot. Linear V - Method editing and Pot. Linear V - Measurements and curvefiles.4.3.9 Chrono AmperometryA potential step induces a current change. The current is recorded while the WORKpotential is maintained at a pre-set value versus the REF potential.Consult the Help file, keyword indexes:Chrono Amperometry - Method editing and Chrono Amperometry -Measurements and curve files.VoltaMaster 4 - Version 7.0x 47Section 4, Chapter 3: Methods available
