Présentation du produit
Les appareils de mesure de la série ION™+ s'utilisent avec des sondes
pour mesurer différents paramètres dans l'eau.
L'appareil de mesure sensION™+ EC71 mesure la conductivité, la salinité,
le TDS et la température. Les données de mesure peuvent être
enregistrées et transférées vers une imprimante ou un PC.

Branchement sur alimentation CA
D A N G E R
Risque d'électrocution Si cet équipement est utilisé à l'extérieur ou dans
des lieux potentiellement humides, un disjoncteur de fuite à la terre
(GFCI/GFI) doit être utilisé pour le branchement de l'équipement à sa
source d'alimentation secteur.
L'appareil de mesure peut être alimenté sur secteur à l'aide d'un
adaptateur d'alimentation universel.
1. Sélectionnez la fiche d'adaptateur appropriée à la prise électrique dans
le kit adaptateur.
2. Branchez l'adaptateur d'alimentation universel à l'appareil (Figure 2).
3. Branchez l'adaptateur d'alimentation universel à une prise CA
(Figure 3).
4. Allumez l'appareil.
