Speed detection

You need to know the speed of the measured machine in some cases. We will describe here how the speed
detection works. In the following text, this chapter can be mentioned.
Detection is done just before the measurement itself after pressing the Start button. During the detection there is
information window displayed in bottom right corner.
If the tacho probe is detected, no other speed detection will happen. The speed is measured by tacho probe.
The highest peaks are found and displayed in the list. The highest amplitude speed in on the top of list. The
spectrum is displayed also. Select the correct value and press OK.
If no value in the list is correct, then select manual entry and enter the speed manually. If no value of speed is
defined in this window, then the readings will be taken without it.
The speed detection is available only when vibration sensor is used for point reading. In other cases the
warning appears. Then the manual entry of speed is required.
If the measurement for speed detection fails, then error message appears. E.g. ICP error.
If the speed value is detected, it is automatically saved to the data header for following measurement in the
same way as the speed value measured by tacho probe. If the speed is measured by tacho probe
simultaneously, the value from the tacho probe has priority when saving.
