Safety informat ion
Be sure to read and observe the following instruc-tions!
The device has been designed in accordance with the state ofthe art and complying with the applicable safety regulations.When operating the device, certain conditions may neverthe-less lead to danger for the operator or damage to the device.
Caution!Commissioning may only be carried out by trained experts.Whenever it is likely that protection has been impaired, thedevice shall be made inoperative and secured against unintend-
ed operation.
The protection is likely to be impaired if, for example: the device shows visible damage the device fails to perform the intended measurements after prolonged storage at temperatures above 70 C after severe transport stresses
Before recommissioning the device, a professional routine testin accordance with EN 61010-1 must be performed. This test
should be carried out by the manufacturer.
Caution!Before commissioning it must be proved that the device maybe connected with other equipment.

Protective w iring of switching contactsRelay contacts are subjected to electrical erosion. Especiallywith inductive and capacitive loads, the service life of the con-tacts will be reduced. For suppression of sparks and arcing,components such as RC combinations, nonlinear resistors,
series resistors and diodes should be used.

Concentration curves / rangessee Pg 114 and the following
The concentration curves of many sub-stances show a maximum. This means that
if the substance concentration continues toincrease and the temperature remains con-stant, the conductivity will drop. Therefore,a one-to-one correlation of values is onlypossible in defined ranges.These partial ranges must be selected asmeasurement ranges in the configuration.

Note:If measurements are taken in containers withA < 110 mm, be sure to choose the samedistance and the same container material(metal/plastic) for calibration.
Caution All calibration procedures must be performed by trained per-

When another sensor is used, its sensor data (cell factor,transfer ratio, measuring frequency, t emperature probe) must
be entered in the configuration menu before calibration. Each time a new sensor is connected, the Stratos must becalibrated.

The measurement process is only interrupted briefly. Duringproduct calibration the sensor remains in the process.Calibration is without TC correction!
Procedure: During sampling the currently measured value isstored in the Stratos. The Stratos immediately returns to meas-uring mode. The calibration mode indicator flashes andreminds you that calibration has not been terminated. Thesample is measured in the lab or directly on the site using aportable meter. The measured sample value is then entered inthe Stratos. The new cell factor is calculated from these twovalues.If the sample is invalid, you can take over the value stored dur-ing sampling. In that case the old calibration values are stored.Afterwards, you can start a new product calibration.

SensocheckContinuously monitors the primary coil and its lines for shortcircuits and the secondary coil and its lines for open circuits.Critical values make the Sensoface sad and the correspondingicon flashes:
The Sensocheck message is also output as error message Err 33.The alarm contact is active, the red LED is lighted, output cur-rent 1 is set to 22 mA (when configured correspondingly).Sensocheck can be switched off during configuration (thenSensoface is also disabled). Exception: After a calibration aSmiley is always displayed for confirmation.
The little smiley in the display (Sensoface) alerts to sensorproblems (defective sensor, defective cable).The conditions for a friendly, neutral, or sad Sensoface aresummarized in the following chart. Additional icons refer tothe error cause.
NoteThe worsening of a Sensoface criterion leads to the devaluationof the Sensoface indicator (Smiley becomes sad ). To reset theSensoface indicator, the defect must be remedied and theStratos be calibrated.
