7.2 General Info
Running Time
This indicator displays the running time in the format hh:mm:ss (hour:min:sec).
Acquisition Buffer State
This buffer should stay low and never turn red (buffer full). If it were to occur
this would mean that the acquisition failed in keeping a real-time
communication.
Last Saved Measurement
This indicator displays the name of last saved file (excluding the current record in
progress if any).
7.3 Dynamic Range
Dynamic Range
These vu-meters display the level of the inputs in dBFS (decibels relative to full
scale).
Color legend: - blue is the current level
- yellow is the maximum level measured
- red indicates that a saturation occurred
Reset Saturation
This button resets the saturation and the maximum level from the Dynamic
Range vu-meters.
When the input type selection is AC or ICP, the interface removes the DC component of the input
signal before the dBFS computation. In this way, the dynamic indicator presents the range occupied
by the AC part of the signal. For the Direct DC input selection, the DC is included in the dBFS
computation.
In some rare circumstances when the DC signal is relatively high for the Direct AC or ICP input
selections, saturation can occur before the DC subtraction. In these circumstances, no AC saturations
are detected but a saturation problem is present. To avoid this saturation detection problem, the
interface tests the saturation before removing the DC component. If saturation is detected at this
stage, the number of the corresponding input on the top of the dBFS indicator turns red.
