Parameters 15 and 16: IEU to 20 mA scaling
Parameters 15 and 16 control the maximum measurement range by setting an IEU value that
corresponds to the 20 mA output signal. This allows you to set the measurement range more accurately
than with parameter 3, which controls the measurement range by setting a multiplier in relation to the
baseline value.
The IEU scale ranges from 0 to several million units. Because of this, setting the IEU value is done with
two parameters. Parameter 15 sets the IEU value in millions, and parameter 16 in thousands.

Parameter value represents × million IEU units
6.
(16) IEU units in thousands
Parameter value represents × thousand IEU unit
This means that for setting 20 mA to correspond to, for example, 125 020 000 IEU, the parameter values
would be as shown in Table 37:

Adjusting the measurement range with parameters 15 and 16 overrides the previous
range settings done using parameter 3.
Parameter 15: IEU units in millions
Parameter 15 sets the million part of the IEU value that corresponds to 20 mA output signal. Parameter
value represents × million IEU units.
