8.3.1
Parameter: Measuring ranges
In this menu you can:
•
Permit or cancel the switching over between measuring
ranges
•
Set the full-scale values
•
Define a hysteresis.
Note
Please note that the range parameters only refer to the
measuring ranges at the analog
outputs (see section
Configuration: Inputs/outputs/pump: Analog outputs (Page 134)). The
display always shows the c
omplete, physically possible range.
8.3.1.1
Parameters: Measuring ranges: Switch ranges
In the second line of this dialog you can set the measuring
range 1 or 2 or pe
rmit autoranging (automatic switching over
between these two ranges).
The 'Actual range
' parameter can have the following values:
•
1
:
The analyzer is set to the smaller range (MR 1).
•
2
:
The analyzer is set to the larger range (MR 2).
•
1/2
:
The analyzer is set to the larger range (MR 2). The start-of-
scale value of the analog output corresponds in this case to
the full-scale value of the smaller range (MR 1), the full-
scale value of the analog output corresponds to that of the
larger range (MR 2).
The result is that the analog output of the analyzer has a
range with zero offset (e.g. 90 ... 100%).
•
AR
:
The analyzer switches over automatically from one range to
the other (AR = autoranging). Setting of the switchover
criteria is described in section
Parameters: Measuring
ranges: Hysteresis (Page 127).
