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.

Input values exponential format

Display position	1	2	3	4	5	6	7	8	9	10
Decimal point	-	•	•	•	•	-	-	-	-	-
Input values	0 ...	0 ...	0 ...	0 ...	0 ...	0 ...	E	-	0 ...	0 ...
	9	9	9	9	9	9		or	3	8
								0

To select the exponential function, the decimal point must be located between the 2nd and 5th decimal position.

Flow units

The base units are m3/h for volume flow measurement, m3/h stand. for standard volumetric flow measurement and kg/h for mass flow measurement.

The flow units can be changed in menu item 1.1.4 "Max.Flow". 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.

Conversion

Formula	New unit (User Def.)	=	A1 Coeff.	*	Base unit
Example:	1 litre / h	=	0.001	*	m3/h
