It is possible here for you to modify various analyzer parameters.
These modifications can only be made within the limits which have
been preset for your analyzer. The analyzer checks parameter changes
for plausibility and rejects them if applicable. Fig. 5-6 shows the menu
sequence (see Section 5.7 for explanation of display elements).
The menu "Parameters" is protected by code level 1.
You can use this menu to select dialogs in order to permit or cancel the
switching over between measuring ranges, to set the full-scale values
and to define a hysteresis.
Notice
Please note that the range parameters only refer to the analog outputs
(see Section 5.10). The display always shows the complete, physically
possible range with the factory-set digital resolution.
In the second line of this dialog you can set the measuring ranges 1 or
2 or permit autoranging (automatic switching over between these two
ranges). The parameter Actual range can have the following values:
S
1: The analyzer is set to the smaller range (MR 1) and does not
switch over the analog output (see Chapter 3, Pin Assignments)
(see Fig.).
S
2: The analyzer is set to the larger range (MR 2) and does not
switch over the analog output.
S
AR: The analyzer switches over automatically from one range to the
other (AR = autorange). Refer to Section 5.9.1.3 for how to set the
switch over criteria.
