Abstract
Methods and systems for detecting an obstruction on a sensor of a fluid analyzer, including a method comprising causing a first calibration fluid to contact the sensor to generate signals indicative of a first electric potential of the first calibration fluid; causing a second calibration fluid to contact the sensor to generate signals indicative of a second electric potential of the second calibration fluid; storing a first response slope; causing the first calibration fluid to contact the sensor to generate signals indicative of a third electric potential of the first calibration fluid; causing the second calibration fluid to contact the sensor to generate signals indicative of a fourth electric potential of the second calibration fluid; storing a second response slope; and storing data indicative of an obstruction on the sensor in response to a difference between the first response slope and the second response slope being beyond a threshold.
