Siemens ULTRAMAT 23 Series - Parameters: Measuring Ranges: Switch Ranges

Note
Please note that the range parameters only refer to the measuring ranges at the analog outputs
(see section Con󹪝guration: Inputs/outputs/pump: Analog outputs (Page 137)). The display
always shows the complete, physically possible range.

In the second line of this dialog you can set the measuring range
1 or 2 or permit 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 o󹪜set (e.g. 90 ... 100%).
• AR:
The analyzer switches over automatically from one range to
the other (AR = autoranging). Setting of the switchover cri‐
teria is described in section Parameters: Measuring ranges:
Hysteresis (Page 130).
