10.6.2.1
The current output gives a measured variable (flow or temperature) in scaled
form as a 0 (4) -20 mA current signal.
The current output is scaled via the "Value 20 mA "and" Value 4 mA "(with
current output 0-20 mA "Value 0 mA"). By default, the "Value 20 mA" parameter
is set to the value for the end of the measuring range, but can be parameterized
as desired within the measuring range, but always bigger than the measuring
range start value. The parameters "Value 4 mA" / "Value 0 mA" define the
measured values for the starting current value, which may also be set freely in
the measuring range.
Note 1: If the value is set smaller than the end of the measuring range, the
accuracy of the output voltage value is reduced.
Note 2: The burden on the current output must not exceed 500 Ω.
10.6.2.2
The voltage output outputs a measurement variable (flow or temperature) in
scaled form as a 0-10 V / 2-10 V voltage signal.
The scaling of the voltage output is done via the parameter "Value 10 V "and
"Value 0 V". By default, the "Value 10 V" parameter is set to the value for the end
of the measuring range, but can be parameterized as desired within the
measuring range, but must always be bigger than the measuring range start
value.
The parameters "Value 0 V" and "Value 2 V" define the measured values for the
start voltage value, which may also be freely set in the measuring range.
Note 1: If the value is set smaller than the end of the measuring range, the
resolution and accuracy of the output voltage value are reduced.
