3-Axis G-Force Datalogger

Model VB300

Introduction

Congratulations on your purchase of the VB300 G-Force Datalogger. 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 85,764 peak acceleration samples and 210 freefall
samples.

This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
