Abstract: A conductive atomic force microscope including a plurality of probe structures each including a probe and a cantilever connected thereto, a power supplier applying a bias voltage, a current detector detecting a first current flowing between a sample object and each of the probes and a second current flowing between a measurement object and each of the probes, and calculating representative currents for the sample and measurement objects based on the first and second currents, respectively, and a controller calculating a ratio between representative currents of the sample object measured by each of the probe structures, calculating a scaling factor for scaling the representative current with respect to the measurement object measured by each of the probes, and determine a reproducible current measurement value based on the second measurement current and the scaling factor may be provided.
