Sensor Docking Station
Analog Sensor Calibration
The Bully Dog Sensor Docking Station is capable of
supporting different brands of analog sensors. In order to
make sure that the information from your particular sensor is
being displayed correctly, you will need to change settings
in your GT or WatchDog based on the specifications of your
sensor. To calibrate the Sensor Docking Station for an analog
pressure sensor, you will need to know the ratiometric output .
Access the calibration settings through the following path on
your GT or WatchDog:
Main Menu > User Options > SENSOR Settings
Set Input Low/High
This is the setting for the range of signal strength sent out
by the sensor. Manufacturers provide this information in the
specifications for each sensor; it is listed as ratiometric output,
and it must be between 0 and 5 volts.
Set Output Low/High
This is the setting for the scaling for the output for each
sensor: in other words, how the sensor’s electric signal
should be interpreted. This information is listed with the
ratiometric output in the specifications provided by the sensor
manufacturer, usually in parenthesis.
Example
You have installed an analog pressure sensor (oil, fuel or air) with the
following information listed in the manufacturer’s specifications:
0.5 to 4.5 volt ratiometric output
(0 psi at 0.5 volts and 100 psi at 4.5 volts,linear between these points)
You should enter the following information into the GT or WatchDog:
Set Input Low: 0.5 (volts)
Set Input High: 4.5 (volts)
Set Output Low: 0 (units)
Set Output High: 100 (units)
