Zusammenfassung:	Methods of fluid handling are disclosed. In one method, a pump fluidly associated with a nozzle is energized to move a first fluid with respect to the nozzle. Pressure fluidly associated with the nozzle is substantially continuously monitored with a pressure transducer fluidly associated with the nozzle during movement of the first fluid. An average of the pressure substantially continuously monitored is calculated. The calculated average is used to determine a threshold. The pump fluidly associated with the nozzle is energized to move a second fluid with respect to the nozzle. Pressure fluidly associated with the nozzle is substantially continuously monitored with a pressure transducer fluidly associated with the nozzle during movement of the second fluid. The substantially continuously monitored pressure is integrated. The threshold is compared with the integrated pressure to determine whether movement of the second fluid was intended or unintended.
