EIS quality indicator by Bio-Logic, Because linearity matters
After an equivalent circuit fit analysis, the charge transfer resistance is over-estimated by 8% with the 400 mA AC amplitude measurement. The THD indicator can be used to detect this non-linearity and help optimize the stimulation amplitude
