3.7 Relationship between measurement range and scaling
52
The printing recorder offers the facility to differentiate between the measure-
ment range for the input signals which are connected and the scaling on the
chart paper.
If the parameter Configuration level 1
is not programmed to linear, X1 or X2, then the selected measurement range is
automatically applied to the scaling. If the characteristic type is linear, X1 or X2
there is no automatic application of the measurement range to the scaling. So
in this case, the scaling should be checked, and altered if necessary (Configu-
ration level 1
Scale).
Example:
The parameter Measurement input is programmed as a resistance thermome-
ter.
Type:
resistance thermometer
Characteristic: Pt100
Connection:
2/3-wire
Dim. unit:
°C
Range start:
-200°C
Range end:
+850°C
Filter:
0.1sec
The measurement range (-200 to +850°C) is automatically applied to the scal-
ing (-200 to +850%).
Example:
The parameter Measurement input is programmed as a current input.
Type:
current
Characteristic: linear
Range start:
0mA
Range end:
20mA
Filter:
0.1sec
The measurement range is not applied to the scaling. The parameter Configu-
ration level 1
Scale can be used to alter the scaling (including the dimen-
sional unit).
