Extech VB300 – Vibration Meter – Frequency Range: 60 Hz, Single Axis Measurement: No, Tri-Axial Measurement: Yes

• Built-in 3-axis accelerometers record the time when shock occurs
• Real time FFT Frequency and Time-Domain Vibration Analysis
• Record storage, transport or operational data over time
• USB interface for easy set-up and data download
• Datalogs 112028 Motion Detection samples per axis, or 168042 Normal samples

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.

G-Force datalogger records and times 3-axis 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.

You can record storage, transport or operational data for real time FFT Frequency and Time-Domain vibration analysis. You 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 datalogger 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. Select X-, Y-, Z-axis or any combination (via software).

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.
