How to open
The Colour Scale information field is located at the left side of the echogram in each Channel view. You can easily change the physical size and shape of the fields. Click on the grey lines between the fields and drag to new
size. Note that this will cause one field to increase in size and another to decrease.
Description
The Colour Scale information field shows you the current colour scale in use for the ME70 presentations. Note that additional functions related to the colour scales are available.

Colour Scale The colour scales used by the ME70 are designed to reflect how strong the echoes are. The echo strength is measured in decibels (dB). In the basic colour scale with 12 colours, each colour represents a 3 dB step. This means that the entire scale covers 36 dB. The dynamic range of the ME70 is much larger. The Colour Scale parameters allow you to change the lower limit of colour scale range to match the current echoes.
Open the Colour Scale dialog box from the shortcut menu.

Bottom bar The colour scale is shown on the bottom bar even when the Colour Scale information field is closed.

TipThe Colour Setup dialog box controls the presentation colours used by the ME70 system. This includes the palette ("skin"), the number of colours in use, and the colour scale when no TVG has been selected for the
presentation You open the Colour Setup dialog box from the Display menu.
The following colour scales are available:
12 Colours |
Sonar Colours |
Smooth ES |
Grayscale |
BI500 Colours |

The Smooth Echosounder scale is based on the standard 12-colour scale. Additional colours have been added between them to make smoother colour transitions.
Example
Within the 12 colour representation the light blue colours represents signals which are weaker in strength, while dark brown
is used for stronger signals. By changing Gain 20Log (or Gain 40Log), the limits of the colour scale are changed. A high numeric
TVG value (= high gain) displays weak echo signals properly, while the stronger signals saturate into dark brown colour. A
low numeric value displays strong echo signals properly. Weak signals below the limit of the colour scale are not displayed
(the display background colour is used) As the number of colours may differ due to colour setup parameters and dedicated colour
schemes can be used, this is subject to change with specific settings.
Details
To activate a field and hence a channel, you must first click in the field. By doing so the menus and options available will
adjust to the activated field and also apply to the active channel for this field. In this context , the phrase channel is
used as a common term to identify the combination of transceiver, transducer and operating frequency.
You can easily change the physical size and shape of the fields. Click on the grey lines between the fields and drag to new
size. Note that this will cause one field to increase in size and another to decrease.
Right-click in the active field and select Hide View from the shortcut menu to close the field.
Right-click in any of the fields in the active channel and select Configure Window to be able to reopen a field.Select the field(s) you want to re-open by ticking of the name in the Show Views listClick on the Apply button for the field to appear
