Subject to change without notice
9.1.3.2 Text Mode
The “Text mode” menu option is used to adapt the cursor to the different types of graphics
(graphics card and monitor). (For service purposes, only.)
9.1.3.3 Graphics
Buffer size for measurement
Buffer size for archive
Both the “On-line” and “Archive” graphic buffers are organized as ring buffers, i.e. the
oldest data are overwritten when new files are saved.
The time range that can be represented as graphics is dependent on:
• Size of the graphic buffer
• Measurement frequency.
The size of the graphic buffers is defined in points.
One point corresponds to 56 bytes and is capable of storing the measured values of 8
calculations.
Default setting:
• Graphic buffer of current file 500 points (28 Kbytes)
• Graphic buffer for archived files 1000 points (56 Kbytes).
The graphic buffers are organized on the hard disk (see Chapter “Directories and Files”
(
→
p. 123, §9.1.3.4)) and can be increased depending on the available storage capacity.
However, it does not make sense to specify a graphic buffer size that exceeds the size of
the current file to be stored.
Automatic pan devisor value
As soon as the display of measured values reaches the right-hand margin of the screen, the
partial view of the graphic display is moved by the nth part of the screen display.
Default setting: 4. This means, the partial view is moved towards the left by the fourth part
of the total screen page.
Max. Numbers of axis points to be marked
Scales the graphic. The axes of the graphic display are divided by a selectable factor.
Default setting: Factor 7. The axes are divided by 7.
Adjustable: 6 ... 11.
Annotation of the axes is automatically carried out in increments of one, two or five,
depending on the selected range to be displayed and the division of the axes.
Dead time of graphic cursor
In order to determine the curve values of the current measurement, the graphics cursor
can be moved across the screen by using the cursor keys. If the cursor is not moved within
the selected dead time while the current measured values are displayed, it automatically
jumps to the end of the graphics display.
Default setting: 10 seconds.
