Product overview
The sensION™+ meters are used with probes to measure various
parameters in water.
The sensION™+ MM374 meter has two measurement channels to
measure pH, ORP (mV), conductivity or ISE (concentration) with a
selective probe. Channel 1 measures one or two parameter individual or
simultaneously and up to two probes can be connected. Channel
2 measures pH, ORP (mV) or ISE. Measurement data can be stored and
transferred to a printer or PC.
Product components
Refer to Figure 1 to make sure that all components have been received.
If any items are missing or damaged, contact the manufacturer or a
sales representative immediately.

Calibration procedure
This procedure is for general use with liquid calibration solutions. Refer
to the documents that are included with each probe for additional
information.
Note: Solutions should be stirred during calibration. For more information about the
stirring settings, refer to Change the stirring settings on page 13.
Note: If Channel 1 is used as a double channel (pH and EC) the temperature will
be measured by the conductivity cell with integrated ATC. The conductivity cell
must be immersed in the pH buffer solution as well during the pH calibration.The
manual temperature modification is not possible.

Produktübersicht
Die sensION™+ Messgeräte werden mit Elektroden eingesetzt, um
verschiedene Parameter in Wasser zu messen.
Das sensION™+ MM374-Messgerät hat zwei Messkanäle zum Messen
von pH, ORP (mV), Leitfähigkeit oder ISE (Konzentration) mit einer
selektiven Elektrode. Kanal 1 misst einen oder zwei Parameter einzeln
oder gleichzeitig, und es können bis zu zwei Elektroden angeschlossen
werden. Kanal 2 misst pH, ORP (mV) oder ISE. Messwertdaten können
gespeichert und an einen Drucker oder PC übertragen werden.

Kalibriervorgang
Dieser Vorgang gilt für die allgemeine Verwendung mit flüssigen
Kalibrierlösungen. Weitere Informationen finden Sie in den Dokumenten
im Lieferumfang der jeweiligen Elektrode.
Hinweis: Lösungen sollten während der Kalibrierung gerührt werden. Weitere
Informationen zu Rühreinstellungen finden Sie unter Ändern der Rühreinstellungen
auf Seite 34.
Hinweis: Wenn Kanal 1 als Doppelkanal (pH und EL) verwendet wird, wird die
Temperatur von der Leitfähigkeitszelle mit integrierter ATC gemessen. Die
Leitfähigkeitszelle muss auch während der pH-Kalibrierung in die pHStandardlösung eingetaucht werden. Die manuelle Anpassung der Temperatur ist
nicht möglich.
1. Gießen Sie die Standard- oder Kalibrierlösungen in die beschrifteten
Kalibrierbecher.
2. Wählen Sie im Hauptmenü mithilfe von oder sowie und den
Parameter KALIBRIERUNG aus. Bestätigen Sie die Auswahl.
3. Wählen Sie gegebenenfalls die Bediener-ID (1 bis 10) aus und
bestätigen Sie die Auswahl.
4. Reinigen Sie die Elektrode mit deionisiertem Wasser, und geben Sie
die Elektrode in den ersten Kalibrierbecher. Achten Sie darauf, dass
keine Luftblasen in der Messzelle vorhanden sind.
