7.4 See Active Historic Function
This function button (See Active Historic of the Additional Functions Tab) is accessible only
when the active controller is ON.
The historic function is used to analyze the behaviour of the controller and to tune the
controller sensitivity. The historic can also be saved on the PC’s hard disk and can be analyzed with
a post-treatment interface (use the Post-Treatment function of the main interface). The post-
treatment interface and the Active Historic function have a simulation module, which is very useful
to tune the controller sensitivity. Here is the Active Historic interface:
Figure 72 : Active Historic interface
The red curve shows the masking sound level historic and the white curve shows the historic of the
noise level measurement with the input used to control the selected output. Use the <<Output and
Output>> buttons to see the historic of the others output channels.
Use the Save Historic for Post-Treatment control to save the historic of all outputs. Use the Post-
Treatment function to open and analyze the historic file (.oba). The button Export current historic
allows exporting the historic data of the current selected output channel in a text format file.
The Simulation button allows you to launch a simulation module, which is very useful to tune the
controller sensitivity. For instance, the following figure presents a simulation for a sensitivity of 15
instead of 13 (default value):
