The reference value for relative measured values can be set here.
This can be a fixed preset value; however, values measured at a different location
or values based on the generator settings and so on can also be adopted automati-
cally as reference values.
●
Bar graph scaling
If the "Autoscale" button is activated, the extreme values that have so far occurred
are used for scaling the left-hand and right-hand scale end value. The scaling can,
however, also be set manually.
The axis can be displayed with linear or logarithmic subdivisions.
If manual scaling was selected, the start and end value of the bar graph must be
entered in the two fields.
If the selected scaling does not encompass all measured values, a red arrow indi-
cates the end of the scale at which the measured value is beyond the range of the
bar graph.
●
Gridlines
The settings Main
Grid and Sub Grid are used to subdivide the bar graph.
Main gridlines which are labeled with the associated numeric values can be added
with different intervals.
Subgridlines are used for further subdivisions; these lines are not labeled.
●
Limits
A lower and/or upper limit can be defined for each measurement result.
If the limit is activated, each measured value is compared with the limit.
The set limits are shown in the bottom part of the combined display and appear as
a red limit marking on the bar graph.
