There may be more than one data-acquisition object in a script, but only one may be running (i.e., acquiring values) at any time. The typical life-cycle of an Rcv object is:
Rcv = RCV.New(Tag, Pstat) ; Create the Rcv
Rcv.SetPlot(Plottype) ; Determine the plot type
Rcv.Run() ; Run the curve
Rcv.Printl() ; Print the curve out to Output
When an Rcv object is run, the potentiostat must be in a Potentiostatic mode.
