1. Introduction
Thank you for buying a Three Axis Accelerometer Kit from Pico Technology.
This Quick Start Guide will help you set up your interface and oscilloscope.
In conjunction with this guide, please also see the PicoScope help manual
installed with the software.
2. Safety warnings
Please review the following safety precautions to avoid injury and
prevent damage to both the interface and surrounding devices.
DO ensure that only Pico Technology approved sensors are used with this
unit.
DO NOT apply a voltage to the BNC or sensor connectors. The BNC connector
is designed to output signals only.
DO NOT use any of this equipment in explosive atmospheres.
The mounting magnet described in this guide has a strong magnetic
eld. Users of pacemakers and insulin pumps must avoid using
this item.
Magnetic media (such as credit cards), analogue watches,
televisions, computer monitors, sensitive electronic equipment,
and mobile storage devices, should all be kept away from this magnet to
avoid permanent damage.
This magnet can attract magnetic materials or other magnets from large
distances, causing trapping injuries. Care must always be taken to prevent
this hazard.
DO NOT give this magnet to small children.

4. Battery replacement
To remove the battery:
1. Place the interface face down and remove
the four securing screws.
2. Remove the base cover
3. Lift the battery away from the connections
4. Place new battery in position, replace the
base cover and secure.
5. Connections
• Connect your PicoScope to your computer using the blue USB cable
supplied.
• Connect the interface box to the PicoScope
by means of the BNC cables.
• Open PicoScope.
• Connect the accelerometer to the three
axis interface.
6. Magnet mounting instructions
DO ensure a correctly prepared mounting surface is available. This is critical
for obtaining reliable measurements.
1. Verify the mounting surface is clean, at and smooth.
2. Slide the keeper off the mounting magnet.
3. Mount the magnet/sensor assembly to the prepared test surface by
gently rolling it into place. This will avoid damaging the surface.
DO ensure that when in storage and in transit the keeper is tted to the
magnet, to protect the magnet itself and nearby objects.
DO NOT mount the accelerometer carelessly as this has the potential to
generate very high (and damaging) glevels.
