摘要： A method for determining a dosed, or metered, volume of an automatic peristaltic sample taker, in the case of which a measured, dosed, or metered, volume of the peristaltic sample taker is corrected by means of a calibration map. In order to improve accuracy in the determining of the dosed, or metered, volume, during a calibration phase, the calibration map is corrected by means of a correction curve, which depends on a negative pressure arising in the suction region of the peristaltic sample taker.

摘要： An analytical device, including: a processing system for treating a liquid sample and for supplying the treated liquid sample to a measuring cell, to the liquid sample; a measuring transducer for registering a measured value of the treated liquid sample variable; a control unit to control the processing system; and an evaluating unit for determining the measured variable based on the measured value registered by the measuring transducer. The analytical device includes at least one first supply container containing a first reagent component, at least one second supply container containing a second reagent component and a mixing apparatus, for mixing a predetermined amount of the first reagent component contained in the first supply container with a predetermined amount of the second reagent component to form a predetermined amount of the reagent.

摘要： In a method for ascertaining burden resistance for a measurement transmitter, which is supplied with voltage via a first line-pair and which transmits a variable electrical-current signal via an electrical-current loop to a control system via a second line-pair, a test-voltage signal is capacitively coupled into the electrical-current loop and an associated electrical-current signal evaluated. An instantaneous value of the burden resistance is ascertained from a characterizing feature of the electrical-current signal, especially an RC time constant. Thus, already at start-up of a measurement transmitter, a burden resistance, which is too high, can be detected.
