With proper care, it will give you years of accurate and reliable measurements. The HOBO Pendant G Acceleration Data Logger is a waterproof, three-channel logger with 8-bit resolution and can record up to approximately 21,800 combined x-, y-, and z-axis acceleration readings or internal logger events. The logger uses a coupler and optical base station with USB interface for launching and data readout by a computer. The logger can be used for a wide variety of experiments, demonstrations and field studies by measuring dynamic acceleration resulting from motion, shock or vibration. It can also detect static acceleration of gravity, making it possible to measure tilt, activity, and inclination. The logger uses an internal three-axis accelerometer with a range of ± 3 g based on micro-machined silicon sensors consisting of beams that deflect with acceleration. These beams are arranged to act as a variable capacitor. As the beams move, the capacitance changes proportionately. This capacitance change is converted to voltage, filtered and measured by the logger, and displayed in the software in units of g-force. A base station, coupler, and HOBOware® software are required for logger operation. Visit for compatibility information. Specifications Measurement range ± 3 g; 29.4 m/s. (96.5 ft/s.)

Plug the USB connector on the base station into an available USB port on your computer. 2. Insert the logger and the base station into the coupler, as shown in the following diagrams. For BASE-U-1, make sure that the logger is inserted in the end of the coupler that has the magnet, and that the ridges on the base station and logger are aligned with the grooves in the coupler. LOGGER Magnet BASE-U-1 & COUPLER Ridge For BASE-U-4 or the HOBO Waterproof Shuttle, firmly insert the optical end of the base station into the D-shaped end of the coupler, and make sure that the ridge on the logger is aligned with the groove in the coupler. To BASE-U-4 or HOBO Waterproof Shuttle COUPLER2-A LOGGER Ridge side down Coupler lever (for use with HOBO Waterproof Shuttle) 3. If you are using the HOBO Waterproof Shuttle, briefly press the coupler lever to put the shuttle into base station mode. 4. If the logger has never been connected to the computer before, it may take a few seconds for the new hardware to be detected. 5. Use the logger software to set up the alarms, launch, and read out the logger. You can read out the logger or check its status while it continues to log (in Normal logging mode only); stop it manually with the software; or let it record data until the memory is full. Refer to the software user’s guide for complete details on launching, reading out, and viewing data from the logger. Triggered start This logger can be configured to start at your command, using the magnet in the coupler to trigger a start. (To log in Fast mode, this is the only way to launch the logger.) 1. Use the logger software to launch the logger with Trigger Start selected. Remove the logger from the coupler. 2. Bring the logger and an empty coupler or strong magnet to the deployment location. Important: Any magnet can trigger a start. This can be helpful, but it can also cause a premature start. Keep the logger away from strong magnetic fields until you are ready to begin logging. 3.
