Setting technological and instrumental ranges facilitates watching the measured variables. If the technological and instrumental ranges are enabled, then watching the measured variables is set in two levels. This watching is ensured by a graphical viewing.
If the option of some range is not checked, then the definition of the minimum and maximum value of these ranges (and setting the color) has no meaning.
If the option of ranges is checked, then the minimum and maximum of these ranges is shown on the scale in the form of the line in defined color (minimum and maximum can have different color) on the position of the defined value. If the value of the measured variable exceeds the maximum limit, then the color of the indicator changes to the color of this maximum. It is analogical when a minimum is under passed.
If both ranges are defined at the same time, then on exceeding the first maximum (less value from both maximums) the color of the indicator changes according to the color of the first maximum. On exceeding the second maximum (greater value from both maximums) the color of the indicator changes according to the color of the second maximum. It is analogical when minimums are under passed.
