Product overview
The sensION™+ series meters are used with sensION+ probes to
measure various parameters in water. Primarily for field use, the portable
meter operates on three AA batteries.
The sensION™+ series meters are available in 5 models:
•sensION™+ EC5—conductivity, TDS, salinity and temperature meter
• sensION™+ MM150—pH, ORP (Redox), conductivity, TDS and
temperature meter
• sensION™+ MM110—pH, ORP (Redox) and temperature meter
• sensION™+ pH1—pH meter
• sensION™+ DO6—dissolved oxygen (concentration and % saturation)
and temperature meter
Installation
C A U T I O N
Personal injury hazard. Only qualified personnel should conduct the tasks
described in this section of the manual.
Install the batteries
WARNING
Explosion hazard. Incorrect battery installation can cause the release of explosive
gases. Be sure that the batteries are of the same approved chemical type and are
inserted in the correct orientation. Do not mix new and used batteries.
N O T I C E
The battery compartment is not waterproof. If the battery compartment becomes
wet, remove and dry the batteries and dry the interior of the compartment. Check
the battery contacts for corrosion and clean them if necessary.
N O T I C E
When using nickel metal hydride (NiMH) batteries, the battery icon will not indicate
a full charge after freshly charged batteries have been inserted (NiMH batteries
are 1.2 V versus 1.5 V for alkaline batteries). Even though the icon does not indicate
complete charge, 2300 mAH NiMH batteries will achieve 90% of instrument
operation lifetime (before recharge) versus new alkaline batteries.
N O T I C E
To avoid potential damage to the meter from battery leakage, remove the meter
batteries prior to extended periods of non-use.
4 English

The meter can be powered with AA alkaline or rechargeable NiMH
batteries. To conserve battery life, the meter will power off after 5 minutes
of inactivity. This time can be changed in the Display Options menu.
For battery installation refer to Figure 1.
1. Pull the release tab on the battery cover and the remove the cover.
2. Install 3 AA alkaline or 3 AA nickel metal hydride (NiMH) batteries.
Make sure that the batteries are installed in the correct polarity.
3. Replace the battery cover.

AVERTISSEMENT
Indique une situation de danger potentiel ou imminent qui, si elle n'est pas évitée,
peut entraîner des blessures graves, voire mortelles.
ATTENTION
Indique une situation de danger potentiel qui peut entraîner des blessures
mineures ou légères.

l'endommagement du matériel. Informations nécessitant une mise en avant
particulière.
Etiquettes de mise en garde
Lire toutes les informations et toutes les étiquettes apposées sur l’appareil.
Des personnes peuvent se blesser et le matériel peut être endommagé si
ces instructions ne sont pas respectées. Si un symbole ‘danger’ ou
‘attention’ se trouve sur l’instrument, une explication est indiquée dans le
manuel.
Lorsque ce symbole est présent sur l’instrument, reportez-vous au
manuel d’instructions pour obtenir des informations relatives au
fonctionnement et/ou à la sécurité.
L’équipement électrique portant ce symbole ne peut être mis au rebut
dans les systèmes de mise au rebut publics européens après le 12 août
2005. Conformément aux règlements nationaux et européens
(Directive 2002/98/EC), les appareils électriques doivent, depuis le 12
août 2005, ne pas être mis au rebut dans les décharges traditionnelles,
mais être, à la fin de leur service, renvoyés par les utilisateurs
européens au fabricant, qui se chargera de les éliminer à ses frais.
Remarque : Pour le retour à des fins de recyclage, veuillez contactez le fabricant
ou le fournisseur d'équipement pour obtenir les instructions sur la façon de
renvoyer l'équipement usé, les accessoires électriques fournis par le fabricant, et
tous les articles auxiliaires pour mise au rebut appropriée.
Présentation du produit
Les appareils de mesure portables de la série sensION™+ s'utilisent avec
des sondes numériques sensION™+ pour mesurer différents paramètres
dans l'eau. Essentiellement destinés à l'utilisation sur le terrain, ces
appareils de mesure portables fonctionnent avec trois piles AA.
Les appareils de mesure de la série sensION™+ sont disponibles en
5 modèles :
• sensION™+ EC5 - appareil de mesure de conductivité, TDS, salinité et
température
• sensION™+ MM150 - appareil de mesure de pH, Eh (Redox),
conductivité, TDS et température
• sensION™+ MM110 - appareil de mesure de pH, Eh (Redox) et
température
• sensION™+ pH1 - appareil de mesure de pH
• sensION™+ DO6 - appareil de mesure d'oxygène dissous
(concentration et % saturation) et de température
Installation
ATTENTION
Risque de blessures corporelles Seul le personnel qualifié est autorisé à
entreprendre les opérations décrites dans cette section du manuel.
Installation des piles
AVERTISSEMENT
Risque d'explosion. Une installation incorrecte des piles peut libérer des gaz
explosifs. Veillez à ce que les piles soient du même type chimique homologué et
qu'elles soient insérées dans le bon sens. Ne mélangez pas des piles neuves et
des piles usagées.
A V I S
Le compartiment des piles n'est pas étanche à l'eau. Si le compartiment des piles
est humide, retirez et séchez les piles et séchez l'intérieur du compartiment.
Recherchez des traces de corrosion sur les contacts des piles et les nettoyer si
nécessaire.

A V I S
En cas d'utilisation de piles nickel métal hybride (NiMH), l'icône d'état des piles
n'indique pas une charge complète après mise en place de piles venant d'être
rechargées (les piles NiMH ont une tension de 1,2 V, les piles alcalines de 1,5 V).
Même si l'icône n'indique pas une charge complète, les piles NiMH de 2300 mAH
atteignent 90 % de la durée de fonctionnement de l'appareil (avant recharge)
comparée à des piles alcalines neuves
A V I S
Pour éviter des dégâts potentiels à l'appareil suite à une fuite des piles, retirer les
piles de l'appareil de mesure s'il ne doit pas être utilisé pendant une durée
prolongée.
L'appareil peut être alimenté par des piles alcalines AA ou rechargeables
NiMH. Pour optimiser la durée de vie des piles, l'appareil s'éteint après 5
minutes d'inactivité. Cette durée est modifiable dans le menu des Options
d'affichage.
Pour l'installation de la pile, consulter Figure 1.
1. Tirez sur la languette d'ouverture du capot des piles et déposez le
capot.
2. Installez 3 piles alcalines AA ou 3 piles rechargeables nickel métal
hybride (NiMH) AA. Veillez à installer les piles en respectant leur
polarité.
3. Reposer le capot des piles.

Branchement d'une sonde
1. Reliez la sonde à l'instrument (Figure 2).
2. Insérez le connecteur de sorte que la tige d'alignement entre dans la
rainure du connecteur femelle.
Remarque : Ne tournez pas le connecteur.

L'affichage présente trois types d'écran :
•Measure (Mesure) - la mesure la plus récente s'affiche avec la
température et le temps de stabilisation.
• Calibration (Etalonnage) - les valeurs d'étalon d'étalonnage et la
température sont affichées durant un étalonnage.
• Standby (Veille) - l'écran est vide, à l'exception de la minuterie de
mesure en bas.
