User's Guide
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.

Mounting the VB300
The VB300 fits securely in the supplied mounting pedestal. Unscrew the pedestal latch and snap the VB300 into the
pedestal. Secure the latch and follow one of the mounting methods below. There are three mounting methods for
affixing the pedestal to the area under test:
1. Magnetically: Powerful magnets are built into the rear of the pedestal
2. Adhesive: Use glue (not supplied) to affix the pedestal to the area under test
3. Screws: Three mounting holes are provided on the pedestal for screw mounting (screws not supplied)

Datalogging Software Program
INSTALLING THE DATALOGGER SOFTWARE
Install the supplied WindowsTM PC Datalogger Software by placing the supplied program disk in the PC’s CD-ROM
drive. If the installation program does not automatically open and provide on-screen prompts (as shown in diagram
below), open and browse the CD-ROM drive, then find and double-click on the SETUP.EXE file included on the
program disk. Follow the on-screen prompts as shown below to complete the installation.
Before running the datalogger software, please connect the VB300 to the PC and install the USB Driver software as
described in the next section.

INSTALLING THE USB DRIVER
The PC will prompt for the USB Driver installation immediately after the main software program is installed. A
window similar to the one shown below will appear to prompt for the installation. Simply click INSTALL to continue.
To install the driver manually, plug the VB300 into an available USB port on the PC. If this is the first time that the
VB300 is connected to the particular port on the PC, the following screen will appear:
Make sure the program disk is still in the PC CD-ROM drive. Select the ‘recommended’ installation and follow the
on-screen prompts to complete the driver installation. If this is a repeat connection of the VB300 to the USB port,
the driver installation process will be automatically skipped.
RUNNING THE DATALOGGER SOFTWARE
With the VB300 inserted in the PC’s USB port, double-click the program icon (located on the desktop) to launch the
program. The main software screen will appear.
Instructions for using the Datalogger Software are contained in the HELP Utility available from the HELP menu in
the software program. Please read the HELP Utility thoroughly in order to fully understand the software and the
related functionality of the VB300.
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.

Basic Datalogger Operation
This section covers only the starting and stopping of the Datalogger’s recording functions. All other information is
provided in the HELP utility within the software program.
1. Configure the Datalogger’s sample rate, motion detection threshold, record mode, LED flash cycle and more
using the supplied software program. Refer to the instructions included in the software program’s HELP utility
to configure the datalogger and to otherwise use the software.
2. If AUTO start is selected in the software, the datalogger will begin logging data the moment the software
window is closed. If MANUAL is selected, press and hold the datalogger start/stop button until the green LED
flashes; the datalogger LED flashes periodically (flash interval time selectable in software) indicating that the
datalogger is recording.
3. To stop datalogging, press and hold the start/stop button while the unit is datalogging. The red LED will
quickly flash indicating that datalogging has stopped. Refer to the LED status table earlier in this manual for
interpreting the LED flash information.
4. Refer to the software HELP utility for transferring the data from the logger to the PC.

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.
1. Remove the two Phillips screws identified with the two smaller arrows in the diagram below.
2. Slide the battery compartment cover in the direction of the larger arrow.
3. Replace the battery with one of the same type (3.6V lithium, ½ AA).
4. 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.
