9. The accelerometer
needs to be mounted solid and level. Vibrations
in the mount will produce noise in the readings.
The
accelerometer is designed to be mounted
solid to the chassis or affixed to the roll
cage. Typically a bracket such as this is
fabricated to mount the unit on the bar
behind the driver seat. Auto Meter points
out that if the mount is not strong enough
to prevent flexing, then the accelerometer
will see vibrations and can provide distorted
acceleration readings. There's more too:
The accelerometer must be mounted so that
the face is directed toward the front of
the vehicle. The unit must also be mounted
perpendicular and level to the ground. There
should be sufficient room in the mount so
that the accelerometer can rotate 180 degrees
in the brackets for calibration. After the
accelerometer has been mounted, simply plug
the connector into the ACC port on the rear
of the computer. |

10. Installation
in a magneto-fired application requires a shielding
enclosure for the computer. Some applications
may require shielding at the pressure sensor
as well. These enclosures need to be constructed
of steel material. Aluminum or stainless steel
do not provide sufficient absorption of EMI
radiation.
For a closer look at the installation process,
have a peek at the accompanying pictures. Much
of the work is simple, but remember, there's
definitely a right and wrong way to install
sophisticated electronic hardware.
