Alignment
Synchro and stepper compass values require alignment unless the ratio is
1:1. If alignment is required a prompt to enter the compass angle appears
when the system is powered on and the system will automatically open the
Heading folder of the Sensors menu. The power up default angle is 000.0°
and the heading readout flashes until aligned.
1. To change the alignment click in the Value field, the text turns
green (editable).
2. Move the trackball left or right to alter the value. The heading
readout changes when the alignment value changes even if the
compass is unaligned.
STW Source Values
The STW folder lists the available STW
sensor data sources with the currently active
sensor source and its value in highlight.
If Computed is selected for the sensor data
source for STW the system continually
computes the values based on other active
types of sensor data received.
To change the STW sensor source and values, do the following :
1. Tick the button next to the source. Whenever the sensor source is
about to be changed a window prompts you to confirm the change.
2. To confirm click the Yes button, or to return to the previous sensor
source and value click the No button.
If no sensor source is currently available the user can enter manual sensor
data.
CAUTION: MANUAL SENSOR DATA
Using manual data is not the normal mode of operation. A sensor
device should be selected as soon as valid data is available.
1. To enter manual sensor data click in the MAN field, the text
changes to green (editable). Move the trackball left or right to enter
the required value and left click to exit edit mode.
2. Click the MAN button to enter the value.
3. Where the sensor is changed the values shown against the
selected data source are applied. If manual data is entered the
STW readout shown in the Indicator Display is displayed in yellow.
