Access to the marker line parameters

1 Make sure that a Graphic display presentation is active.

2 Press the ENT button to open the Graphic setup

dialogue.

3 The Marker line parameter allows you to switch the

marker line on or off for sensors S1, S2 and S3.

Depth and Height marker lines

The purpose of these marker lines is to provide an easy way to

monitor the depth of the gear. The Height sensor measures the

distance from the seabed and up to the sensor, while the Depth

sensor measures the distance from the sea surface and down to

the sensor.

1 Identify which of the sensors that are the Depth and/or

Height sensors.

2 Set the applicable marker line(s) to ON.

3 Enter the preferred settings for Marker line thickness

and Marker line delay.

4 Press ENT to save the settings and exit to the graphic

display presentation.

The Depth and Height marker lines are presented on the

Graphic display with continuous lines in the same background

colour as in the Numeric display. To read the depth, consult the

depth range on the right side of the display, or the readout in the

Numeric display.

Spread marker line

The purpose of this marker line i s to provide an easy way to

monitor the distance between the trawl doors.

1 Identify which of the sensors that is the Spread sensor.

2 Set the marker line to ON.

3 Enter the preferred settings for Marker line thickness

and Marker line delay.

4 Press ENT to save the settings and return the the graphic

presentation.

The Spread marker line is presented on the Graphic display

with a continuous line. The colour of the line is the same as the

background colour in the numeric presentation. To read the

distance between the trawl doors, consult the depth range on the

right side of the display, or the readout in the Numeric display.

If the trawl door distance is reduced or incr eased, this will be

easily detected as the marker line moves up or down. Note that

you do not monitor the depth of the trawl doors even though

you use the depth scale, the scale is used as a range scale.
