IntroductionIntended UseTheStratosProA2...MSOXYisusedfordissolvedoxygenandtem-perature measurement in biotechnology, pharmaceutical industry, as well as in the field of industry, environment, food processing, and sewage treatment.The sturdy molded enclosure can be fixed into a control panel or mounted on a wall or at a post. The protective hood, which is avail-able as accessory, provides additional protection against direct weather exposure and mechanical damage.The device has been designed for digital standard sensors as well as fordigitaltracesensors(Option).Plain-textmessagesinalarge,backlitdisplayallowintuitiveopera-tion. The colored display backlighting signals alarm messages (red) or HOLDmode(orange).Dianostics functions are provided by “Sensocheck“ and “Sensoface“ monitoring and indication of the sensor condition. The internal log-bookcanhandleupto100entries–upto200withAuditTrail(TAN).The device provides two parameter sets which can be switched manually or via a control input for different process adaptations or different process conditions (e.g. beer and CIP).Password protection for granting access rights during operation can be configured.Twofloating,digitalcontrolinputs(“Hold“and“Control“)areavailablefor external control.The device provides two current outputs (for transmission of mea-sured value and temperature, for example).

Operating ModesDiagnosticsDisplay of calibration data, display of sensor data, performing a device self-test,viewingthelogbookentries,displayofhardware/softwarever-sions of the individual components. The logbook can store 100 events (00...99). They can be displayed directly on the device. The logbook can beextendedto200entriesusingaTAN(Option).

HOLDManualactivationofHOLDmode,e.g.forreplacingadigitalsensor. The signal outputs adopt a defined state.

CalibrationEvery sensor has typical characteristic values, which change in the course of the operating time. Calibration is required to supply a cor-rect measured value. The device checks which value the sensor delivers when measuring in a known solution. When there is a deviation, the de-vice can be “adjusted“. In that case, the device displays the “actual“ value and internally corrects the measurement error of the sensor. Calibration must be repeated at regular intervals. The time between the calibration cycles depends on the load on the sensor. During calibration the device isinHOLDmode.During calibration the analyzer remains in the HOLD mode until it is stopped by the operator.

ConfigurationTheanalyzermustbeconfiguredfortherespectivemeasurementtask.In the “Configuration“ mode you select the connected sensor, the mea-surement range to be transmitted, and the conditions for warning and alarmmessages.DuringconfigurationthedeviceisinHOLDmode.Configuration mode is automatically exited 20 minutes after the last keystroke. The device returns to measuring mode.

CalibrationCalibration adapts the device to the individual sensor characteristics. It is always recommended to calibrate in air. Compared to water, air is a calibration medium which is easy to handle, stable, and thus safe. In the most cases, however, the sensor must be dismounted for a calibration in air.When dealing with biotechnological processes which require sterile conditions,thesensorcannotberemovedforcalibration.Here, calibration must be performed with aeration directly in the process medium(e.g.aftersterilization).In the field of biotechnology, for example, often saturation is measured and calibration is performed in the medium for reasons of sterility. Forotherapplicationswhereconcentrationismeasured(watercontroletc.), calibration in air has proved to be useful.

Please note:Allcalibrationproceduresmustbeperformedbytrainedperson-•nel. Incorrectly set parameters may go unnoticed, but change the measuring properties.
