131.5.3 DO Sensor ActivationThe DO probe is shipped dry. To hydrate the sensor and prepare it for use, pro-ceed as follows:• Remove the black & red plastic cap. This cap is used for shipping purposesonly and can be thrown away.• Insert the supplied O-ring in the membrane.• Rinse the supplied membrane with some electrolyte solution while shaking itgently. Refill with clean electrolyte. Gently tap the membrane over a surface toensure that no air bubbles remain trapped. To avoid damaging the membrane,do not touch it with your fingers.• With the sensor facing down screw the cap clockwise to the end of the threads.Some electrolyte will overflow.1.5.4 InstallationThe multisensor probe can support 3 different sensors: DO, EC, pH or pH/ORP.To make easier the installation, the sensors are color coded.For a correct installation, proceed as follow:• Grease the O-ring gaskets.• Insert the sensor while paying attention to the correct alignment with the corre-sponding colored connector. Fix the sensor by screwing the locking nut withthe supplied tool.• When all sensors are mounted, screw the protection sleeve for taking mea-surements or the transparent beaker for calibrating.• With the meter off, connect the probe to the DIN socket onthe bottom of the instrument by aligning the pins and push-ing in the plug. Tighten the nut to ensure good connection.pH/ORP probeDO probeEC probeProbe withcalibration beakerProbe withprotection sleevepH/ORP probeDO probeEC probeProbe withcalibration beakerProbe withprotection sleeveTemperaturesensor
