The function of the sensors is as follows: the left most
sensor is equivalent to left key, the right most, the right
key, and the top, the center key.
The converter is capable of displaying several types of measured values (depending on the

bottom line. Depending on the programming of Function 3.03.07 CYCL DISP, they can be

intervals.
Depending on the programming of Function 3.03.08 ERROR MSG, errors are indicated by
flashing display lines and/or by the compass field. For a description of the errors and what to do,
see main menu Error/Totalizer.
