Measurement ranges definition of voltage inputs
( U
version
)
The nominal range of input current for each input is 0-5V, 1-5V, 0-10V or 2-10V and can
be extended to the maximum of 0-12 V, independently to each measurement channel. The
range of measurement results corresponding to the nominal range of input voltage is defined
as
user defined range
. The range of measurement results corresponding to the range of input
voltage including the extensions is defined as
allowable measurement range
). All
values presented as sliders are scaled due to
user defined range
. Graph is scaled due to
allowable measurement range
.
*
"Lower ext."
parameter is only significant for an input current range of 1-5V and 2-10V.
Fig. 6.2. Definition of measurement ranges (
U version
)
The range of displayed values, unit of measured value and position of the decimal point
(for presentation in numeric form) and name of channel are defined by the user.
6.1.3.
Measurement ranges definition of RTD inputs
(
RTD version
)
The range of every input's measured signal is selectable, and user defined as
user
defined range
. All values presented in graphic form (graphs, sliders) are scaled due to
user
defined range
.
The range of the results referred to maximum hardware performances is
defined as
allowable measurement range
).
Fig. 6.3. Definition of measurement ranges (
RTD version
)
The range of the displayed values, type of input signal, scale bias, and name of the
channel are defined by the user.
