NeVib allows not only to take measurements, but also to import measurements from other sources.
NeVib supports import of text files in ASCII, as CSV files. The exact format of the file may be specified.
Click menu 'File - Import measurement from ASCII file'
the file to be converted may be selected
the import dialogue opens:
Click on a region on the image to learn more about a special subject.
Import expects, in each line of the ASCII file several floating point numbers with the following meaning:
Files with one vibration measuring point with three axes:
Time in seconds / X-value / Y-value / Z-value
Files with two vibration measuring point with three axes:
Time in seconds / X-value1 / Y-value1 / Z-value1 / X-value2 / Y-value2 / Z-value2
Example with one vibration measuring point, four head lines, value separator semicolon, decimal separator comma:
Measurement of 1.4.1703

Using the time values of two consecutive lines the sample rate is calculated.
At the beginning of the file any number of descriptive headers may be included,
which are skipped during import. In the above example there are four headers.
NeVib can handle measurements with one or two triaxial vibration measurement points.
If the ASCII file containing the data of one vibration measurement point, enter here
a 1 if it contains the data of two vibration measurement points, a. 2
Between the times and the measured values and between the measured values there are delimiters.
Please select here the delimiter, which is located between the readings, in the example above, a semicolon.
In German-speaking countries a comma is used as is as decimal separator, in the English-speaking countries a point.
Here you can select the appropriate decimal separator.
If the acceleration readings are measured in "g", the will be multiplied by 9,81, because NeVib uses accelerations in m/s².
