Smart Systems User’s Manual Version 1.1

Arrow Reference

Section 5.4.1 describes the Back-up Arrow that appears when a Smart System is

backed up. The Back-up Arrow allows the user to pinpoint the exact ground position

corresponding to a target response on the data image. The Arrow Reference value is

used to change the physical position that corresponds to the Back-up Arrow. If the

Arrow Reference value is set to the default value of zero (0.0) metres, the Back-up arrow

position corresponds with the center point of the Noggin.

However, the Arrow Reference value can be changed so that the Back-up Arrow

corresponds to a position at any offset from the center of the Noggin. For example,

setting the Arrow Reference value to +0.25 meters moves the Back-up Arrow to line up

with a position 25 centimeters in front of the Noggin centre point (on the Noggin 500

Smart Cart this roughly corresponds to the front axle). Setting the Arrow Reference

value to -0.25 meters moves the Back-up Arrow to line up with a position 25 centimeters

in behind the Noggin centre point (on the Noggin 500 Smart Cart this roughly

corresponds to the back axle). In this way, the Arrow Reference value can be changed

to correspond with any position desired by the user.

One reason the user may want to change the Arrow Reference value is so that the

Noggin does not cover the actual target location. This makes it easier to spray paint a

mark or put a flag on the ground where the target occurs.

To change the Arrow Reference value, use the Increase and Decrease buttons. The

Increase button will increment the value by 0.025 meters or 2.5 centimeters. The

Decrease button will decrement the value by 0.025 meters or 2.5 centimeters. Positive

values correspond to positions in front of the Noggin and negative values are positions

behind the Smart Cart. Note that the Arrow Reference value is always expressed in

metres regardless of the settings of the other units. When the Arrow Reference value

has been set, press 4 to save it.

1) Increase

2) Decrease

3) Set to Zero

4) Save and Return

Window Zooming

Window Zooming allows the user to double or half all the default depth settings. For

example, if the Window Zooming is set to the default of 100%, the user may find the five

Depth settings to be 2.5, 5.0, 7.5, 10.0 and 15.0 metres. If the Window Zooming option is

changed to 50% then the Depth settings are reduced to one half, specifically 1.25, 2.5,

3.75, 5.0, and 7.5 metres. Similarly, if The Window Zoom option is set to 200% then the

Depth settings are doubled, specifically 5.0, 10.0, 15.0, 20.0 and 30.0 metres. This

option allows the user to make larger or smaller depth ranges than the default.

The choices available are:

1) 50%

2) 100% (default)

3) 200%
