Claim:
1. A calibration method for a galvanic tool, comprising: determining an internal coupling impedance between at least two electrodes of the galvanic tool; inputting the determined internal coupling impedances into an equation used to evaluate the response of the galvanic tool; generating voltage and current measurements from the galvanic tool using a calibration device; determining a leakage current value through at least one of the two electrodes based, at least in part, on the voltage and current measurements and the equation; receiving one or more voltage measurements from the galvanic tool; storing the leakage current value; and calibrating the received one or more voltage measurements using the stored leakage current value, wherein calibrating the received voltage measurements comprises adjusting the received one or more voltage measurements based on the stored leakage current value.
