Extech VB300 3-Axis G-Force USB Vibration Datalogger
Records and times 3-axis shock and peaks
The Model VB300 can measure and record shock and vibration (acceleration) readings over its ± 18g measurement range. This device will record 3-axis g-force and related peaks to provide a history of shock and vibration conditions. The real time clock provides time stamps for all data.
The user can easily configure the logging rate, high/low alarm and start-mode, and download the stored data by plugging the VB300 into a PC's USB port and running the supplied PC software. Measurement data can be plotted, printed and exported for use with other applications such as word processors and spreadsheets. The data logger is supplied with a long-life 1000 hour lithium battery.
The VB300 memory uses a 4MB Flash device that can hold 168042 Normal recordings or 112028 Motion Detection recordings per axis.

Battery Replacement
The VB300 does not lose its stored readings when the battery expires or when the battery is replaced. The data logging process will however be stopped and cannot be re-started until the battery has been replaced and the logged data has been downloaded to PC.
The battery life is rated for approx. 1000 hours. If in doubt, replace the battery before logging critical data. Use only 3.6V lithium batteries. Before replacing the battery, remove the datalogger from the PC.
Note: When the VB300 is connected to the USB port, its battery discharges at a higher rate than normal. To conserve battery life, do not leave the VB300 connected to the USB port for a prolonged period of time.
- Remove the two Phillips screws identified with the two smaller arrows in the diagram below.
- Slide the battery compartment cover in the direction of the larger arrow.
- Replace the battery with one of the same type (3.6V lithium, ½ AA 1.0Ah, Saft LS - 14250 or equiv).
- Close the battery compartment and tighten with the two screws.
WARNING: Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations.
