6.2.5 Changing units
When entering numbers and values in floating point format, the maximum possible accuracy is
0.003%. The accuracy depends on both the position of the decimal point and the length of the
number entered.
Numerical values and factors are displayed in the first line of the 10-digit display. Numerical
values are either displayed in floating point format (123.4567890) or are expressed in exponential
format (123456E002). The conversion factor of the totalizer and the pulse output is, however,
expressed in whole numbers.

User defined units can be entered using "User Def."
The unit (text) as well as the conversion factor (number) can be entered here.
The conversion factor must always be entered based on the base unit.
