Time basis
: Allows to set the time basis per division.
NB : We can have a rectangular visualization : for example, for a speed of 500 ms/div, if
100 channels are validated, the sampling period will be of 100ms, and we will have then 5
points per division and 50 points on the entire screen, hence the rectangular effect.
Full screen
: Allows to visualize the graph on the entire screen. (pressing once on the screen
displays the previous screen).
Mathematical calculation
: allows to display values of mathematical calculations on screen.
(To access the mathematical calculations, you have to validate them previously in the
“Screen setting”
window)
4.11.2.
Numerical window
The numerical window allows to visualize in real time the values
of each channel.
1.
The or
keys : allow to choose the group to view
2.
By pressing a specific channel :
o
The graph terminals are bound to this channel.
o
In real time acquisition, the instant value will show up.
o
By visualizing the cursors; then the difference value
between cursors as well as T1 and T2 values
corresponding to cursors T1 and T20 will be displayed.
3.
Key: allows to validate/cancel the display of this window.
4.11.3.
Graphical window
The reticle of the graphical window is divided into 10 divisions, the visualization of the total
curves is 10 times the time basis (for 1s/div, we have 10 seconds of graphic).
The number of visualized points is 1000 (100 per division).
The number of screen can be set in the « screen setting » window.
The right terminals are bound to a valid channel: you just have to press on that channel in
the numerical window.
