Events are independent occurrences triggered by a logger activity such as Bad Battery or Host Connected Events help you determine what was happening while the logger was logging The logger stores 64K of data and can record over 42 000 12 bit measurements Deploying and Protecting the Logger e To clean the logger s case use a sponge with warm soapy water e Use the included clamp to mount the logger to a surface The clamp has two holes for the screws 44 mm 1 7 inches apart The clamp is slightly tapered to accommodate the logger Install the clamp so the logger is oriented with the communication window facing up or to the side This will prevent condensation from pooling on the sensor or cable grommet e A solar radiation shield is recommended if the logger or its sensors will be exposed to sunshine Drip Loop e If the logger housing will be in sunlight slide the included protective cap over the logger communication window to protect the window against UV light RA ann UV Protective Cap Drip Loop e When mounting the logger be sure to attach the logger so the logger cable is not being pulled Also leave about 5 cm 2 inch of drip loop in the cable where it comes out of the logger as shown in the above diagrams to prevent water from entering the logger housing e Periodically inspect the three desiccant packs located in the logger cap If they are not bright blue dry them following the instructi
