Check whether the potentiostat works normally, what parameters do we mainly see? The difference between spontaneous potential and reference potential

Output voltage, current and ordinary there is no difference, with a false load can detect the working state of the instrument. If there is no alarm, potential, current is stable, indicating that the work is normal. Metal materials have a natural erosion point in the soil, which varies with the environment. This is not usually said for reference potentials. It's either the scale potential or the on-off potential. So there's no comparison
