Abstract
Methods, systems, and computer program products for measuring a capacitance between a probe and a liquid, pausing movement of the probe based on a rate of change of the capacitance, further measuring the capacitance while the probe is paused, and, based on the further measurements, performing one or more of: resuming movement of the probe, determining a position of the probe, aspirating liquid into the probe, and dispensing from the probe. Resuming movement of the probe can include returning iteratively to measuring a capacitance, and the further measuring can be performed for a time interval that can vary based on the further measured capacitance(s), a probe movement characteristic, and/or a sampling rate.
