Too-low voltage alarm:
If the value of the battery is less than 10,8V for 12V voltage or 21,6V for 24V voltage or if it is
greater than the value 15V for 12V voltage i.e. 30V for 24V voltage, that is shown by a
blinking battery symbol (sign).
Tank compensation:
A special setting – correction is required for irregularly-shaped tanks. With the help of
compensation values, the representation can be adapted so that it is as realistic as possible.
For data entry, the tank when it is half full (that is half the tank), is required.
