2. When a USB cable is attached for the first time, the Found New Hardware wizard opens. Run the
new hardware wizard to install the USB driver for the logger. When finished, the message “Your
new hardware is installed and ready to use” is shown. In the event the wizard does not run or the
install fails, contact technical support to assist with trouble shooting your specific operating

Sensor Hazardous Locations and RF Exposure Hazards. Some sensors have RF radiation exposure
hazards and are used in explosive atmospheres. See sensor manual warnings and instructions before
connecting a sensor to the logger.
The number of sensors that can attach to the logger varies with the model of the logger. Some
sensors must attach to an external module that is used as an interface between the sensor and the
logger.
Figure 7 shows the AV9000 Area Velocity Analyzer module on the side of the logger and the
connection to a submerged area/velocity sensor.
1. If the sensor cable has connectors on both ends, attach the cable to the sensor first.
2. Attach the sensor (or module) to any SENSOR port on the logger ( Figure 6 or Figure 7 ). Tighten
the connector by hand.
Note: For rain gauges, attach the sensor to the RAIN connector.
3. If the sensor uses an external module, attach the module to the logger, then attach the sensor to
the module (
Figure 7 ).
4. If the sensor cable has a desiccant hub, align the desiccant hub vertically and make sure that the
air port points down (
Figure 6 ).
