The bar graphs are in a logarithmic scale so that the presence of both low-level
and high-level signals can be seen. The readings show the minimum, maximum,
RMS, and Peak levels for the units set in the channel setup table. If the input units
are in acceleration, then the signal is integrated to show the velocity peak and
double integrated to show the displacement peak. The integration is done digitally
and should only be taken as estimation; the accuracy should not be relied on.
The Overload column shows when a channel is overloaded due to an input signal
exceeding the input maximum. Readings from an overloaded channel should not
be used.
Channel status information can be updated by right-clicking in the window and
selecting Start Refresh when a test is not running.
Once a window is created with a type and combination of displayed signals, it can
be saved as a custom window template. To save the current window layout, select
the window and choose Save Active Window as User Defined under the
Display menu. After saving, this template will be available under User Defined
Windows in the Display menu.
Signals can also be added to existing windows. Dragging a signal from the signal
list to a window will display it in the window. You can also right-click on the signal
and select Add to the Active Window. Note that the target window for the
signal must be a valid option for the signal type.
