LMP91000: HOW TO CALIBRATE SENSOR

Dear Hendry - 

Welcome to the E2E Forum and thanks for posting!

From what I could gather on this topic, this is a non-destructive method of determining the corrosion rates of metals that basically involves the sensor being excited and the potentiostat sweeping the metal under examination

This seemed like a good reference to share: https://www.gamry.com/application-notes/corrosion-coatings/basics-of-electrochemical-corrosion-measurements/

I think once you get a reference device to compare what you are developing to and go through the math like what i can see in the link provided, it might become clear what the settings should be on the LMP91000 and what calibrations you may need to do to your system (not the LMP91000 itself). 

Dear Hendry - 

I would recommend using a reference sensor and the EVM, in the physical configuration you intend. Perhaps a 2 lead cell configuration as is done with O2 sensors, start with a configuration from the sensor database in the GUI, and modify until you get to reasonable values first, then check over temperature, then go look for things you may have to tweak or "calibrate" - for example, the cable connection between the sensor and the AFE is usually something that is needed to be attended to when designing low power measurement systems.  

Hendry - 

I meant that you would create a reference system, with known good working components, as you develop your sensor.
