I am a student at University College of London and working on an electrochemical project to measure corrosion rate of steel. I have an analogue potentiostat, which I need to read out current output (converted to voltage) from it, in order to plot Current versus Voltage graphs (i.e. Cyclic voltammetry).
I am new to data acquisition hardwares and softwares, so i would very much appreciate and be grateful to any help on this matter.
I have connected the Voltage control on the potentiostat to the Analogue output on my LabJack U3. Is that right? or I should connect it to Analogue input instead?
I also connected the current output (converted to voltage) from the potentiostat to the analogue input of my labjack U3. Is that correct?
In Cyclic Voltammetry experiment, you apply voltages in a specific range (e.g. 0.5 to 1.5V) in a specific time (like 10mV/sec) then you monitor the current. So the potentiostat I am using (Bank MP 81) has two analogue voltage terminals. (one for the voltage control and one for the current(converted to voltage) output). My aim in using the LabJack is to login the two potentiostat output channels and save them in a file for future analysis. I want to have current versus voltage graphs at the end. I am planning to use DAQFactory software for this purpose.
From my readings through the Forum, i know that I have to use Stream mode in DAQFactory but as I said I have no background knowledge and I dont knot how to go about this problem. Thank you very very much for your held and time.
