Choosing MSG.OFFSET = 1 the display has ignored all the characters prior to the first
numerical value, without the need to count them.
It is important to choose MSG.CURSOR = 4 ("15.8" is made up of 4 characters "."
included), since after the first number the viewer will try to display everything up to the end block.
If NOT selected, the following displays would be obtained. Since display cannot present
some characters (like k and g), it displays "-".
