The user should connect the correct sensor to the unit with the parameters displayed in window. Confirm by
pressing Ok. The setting in Sensors will be rewritten by point setting in route. You can made changes in setting
now using the Sensors button.
The sensor can have defined the name in DDS (e.g.ACC100). It should help the user in field to use
correct sensor. These names are checked in instrument. When the names are not the same, then the Used
Sensor window appears. No checking of other parameters is done.
Route START Button start, start next
"start next" enables immediate start of measuring on next point.
The next machine will be displayed after the last point in the machine.
Display Small Values on, off When you are interested to see values under the 0,001, then set it to on and
the values will be displayed in exponential form ( e.g. 5,26E-6). Otherwise the 0 (zero) will be displayed.
ICP Initialisation Delay[s]
default, user the time delay after the ICP is switched on
Stop if ICP Error
on
the measurement is stopped, when ICP error occurs
off
the measurement continues, ICP error is only information
Units metric, imperial, both ( all units appears in the menu)
Frequency unit
Hz, RPM, CPS, CPM
Speed unit
Hz, RPM, CPS, CPM
Power/Line Frequency
it is used for Elect value in Synch table, which is displayed for spectra
Phase range (-180, 180) , (0, 360)
the range of phase values
Displayed Spectra in Cascade
32, 128, 256, 512, 1024
the number of displayed spectra in
cascade graph. It is not the number of measured spectra !

Align Graphs on, off
if more graphs of the same type are displayed, then the Zoom and Cursor
function of all graphs can be aligned.
Graph Grid
on,off
Cursor Type
linear, maxs
this item must be deeply explained. The graph width (e.g.spectrum frequency
axe) is displayed on the approx. 600 screen pixels. But the spectrum could have 25600 lines and then 42 lines
is displayed in one pixel line ( 42=25600/600). This number of lines in one graph pixel is different for other total
line number and used zoom. In the older VA4 version we used the cursor movement procedure by lines. It
means that the cursor moves inside one pixel without any real move on the screen. The users complained about
it. In the version 2 we have used another procedure. The cursor moves by pixels, not by lines. In each pixel is
hidden more lines and the cursor must display one specific line. What line should we use? When the Cursor
type is set to linear, then the step of cursor movement is the number of lines in one pixel. When the maxs is set,
then the cursor is always move to the maximum line, which is contained in one pixel.
Record analysis speed
fast, real tíme
the record could be analyzed in two ways. Let's
suppose the record length is 300 sec, it could be e.g. run up record. You want to measure the 1x amp+phase
(ampl+phase+speed) during the record. If you want to watch the continuous results, then select the real time
mode and the processing of record will take 300 sec (the analyzing time is the same time as the recording time
