Potentiostat dummy cells

One of our most frequently asked questions on the Forums and via email is how to produce a calibration for the Cheapstat potentiostat. The Cheapstat potentiostat returns measured current values as raw unitless integers read from the ADC (analog to digital converter) at the output of the transimpedance amplifier (current to voltage converter). These integer values are proportional to the current flowing into the working electrode. To convert these unitless integer values to current measurements you need to use a calibration. This can be done using a dummy cell consisting of a single resistor of known value R.  We recently designed a potentiostat...
