From your data browser window,
highlight any lap or group of laps
that you wish to view / edit the properties of then press this button on the tool bar.
Example of the use of a file constant:
DATAVIEW Pg. 60/133
During the download process Constants may be created and
attached to any data file that is captured from a specified data
logger.
Constants may be used within Virtual channels to make your
mathematical output specific to the data from each logger.
Within this Constants menu it is possible to view any Constants
that have been allocated during download, add any new ones as
you want, or edit the values of any.
Constants may be saved or loaded into other data file sets using
the Load and Save As functions
For more information see section 3.9
To work out the mathematical spring load based on spring movement the mathematics would be a simple mm of
movement x spring rate. Where the mm of movement is measured using the logger as a variable value and the
spring rate is a fixed constant.
Now consider a comparison of two peaces of data where the spring rate is different for each. The mathematics must
now be mm of movement from data file 1 x spring rate 1 compared to mm of movement from data file 2 x
spring rate 2.
The spring rate is defined using the data file constants so that the mathematical comparison remains accurate.
