In Normal mode, the logger’s fastest logging interval is once per second. Normal mode is ideal for applications involving tilt, activity, and inclination. These applications do not require information about the dynamics of the acceleration events, but rely more on the static acceleration of gravity. Fast mode allows logging intervals between 0.01 and 0.99 seconds (100 to 1.01 Hz), making it ideal for applications involving vibration and shock. These applications are more concerned with the dynamics of the acceleration events over short periods, and would not be captured in Normal mode. Important: Connecting the logger to the computer (or a shuttle) when logging in Fast mode will stop the logger. The logger’s memory can store roughly 60,000 measurements. The time required to fill this memory depends on how many channels and events are being logged, as well as the logging interval. For example, if you log x-, y-, and z-axis acceleration at 100 Hz, the logger’s memory will fill up in less than four minutes. An estimated duration, based on the logging interval and channels you select, is displayed on the Launch window in HOBOware. HOBO Pendant G Acceleration Data Logger Operation A light (LED) on the front of the logger confirms logger operation. The following table explains when the light blinks during logger operation. When: The light: The logger is awaiting an Interval, Delayed, or Trigger Start Blinks once every eight seconds until logging begins. Logger is subjected to a magnetic field Blinks once every second when the magnet is present, then (Normal mode only) blinks rapidly three times when logging begins. The logger is logging in Normal mode Blinks once every one to four seconds (the shorter the logging interval, the faster the light blinks); blinks when logging a sample The logger is logging in Fast mode Blinks once every quarter-second Mounting the logger The provided mounting bracket offers two orientation options for securing the logger to a rigid surface. Secure the bracket to the object of interest, then use the mounting screw provided to attach the logger to the bracket. Protecting the logger The logger can be damaged if the water depth rating is exceeded. The depth rating is approximately 30 m (100 ft) at temperatures below 20°C (68°F), but is less in warmer water. Refer to Plot B for details. Do not store the logger in the coupler. Remove the logger from the coupler when you are not using it. When the logger is in the coupler or near a magnet, it consumes more power and will drain the battery prematurely. Keep the logger away from magnets. Being near a magnet can cause false coupler events to be logged. It can also launch the logger prematurely if it is waiting for a trigger start. Note! Static electricity may cause the logger to stop logging. To avoid electrostatic discharge, transport the logger in an anti-static bag, and ground yourself by touching an unpainted metal surface before handling the logger. For more information about electrostatic discharge, visit Periodically inspect the desiccant and dry it if it is not bright blue. The desiccant pack is located in the cap of the logger. To dry the desiccant, remove the desiccant pack from the cap and leave the pack in a warm, dry location until the bright blue color is restored. (Refer to the “Battery” section for instructions on removing and replacing the logger cap.) Temperature range Desiccant maintenance schedule Less than 30°C (86°F) Approximately once per year 30° to 40°C (86° to 104°F) Approximately every six months Over 40°C (104°F) Approximately every three months Factory calibration The logger is factory-calibrated and does not require any additional calibration. To verify proper calibration, check the logger’s status (when it is not logging) in the HOBOware software to check the logger’s response to gravity. When any of the axes are held horizontally, you should see a reading close to zero. When held vertically, with the arrow facing downwards, the response should be close to 1 g. Battery The logger requires one 3-Volt CR-2032 lithium battery. Battery life varies based on the temperature and the frequency at which the logger is recording data (the logging interval). A new battery typically lasts one year with logging intervals greater than one minute. Deployments in extremely cold or hot temperatures, or logging intervals faster than one minute, may significantly reduce battery life. Continuous logging at the fastest logging rate of 0.01 seconds (100 Hz) will deplete the battery in as little as one week. To replace the battery: 1. Remove the two screws that secure the end cap to the case and remove the cap. 2. Examine the desiccant pack that is tucked into the cap. If the desiccant is not bright blue, put the desiccant pack in a warm, dry place until the blue color is restored. 3. Gently tap the case to loosen the circuit board and remove it from the case. 4. Carefully push the battery ...
