Bronkhorst FlowPlot - Manual (Page 19)

BRONKHORST ®
3 SPREADSHEET DATA
While FlowPlot is plotting, in the background a comma separated file can be filled with the samples that are taken.
The location and filename of this file can be set at the Options window at the File locations tab, as can saving to the
file be enabled or disabled.
Each time FlowPlot runs from the start of the graph, a new file is generated by adding the actual date and time to the
specified filename. The spreadsheet file can be opened by means of e.g. Excel for further data analysis. Every odd
column contains the time value, while every even column contains the value of the parameter.
Changing the poll times in FlowDDE (poll time for normal and realtime poll time for realtime measurement) will
influence the amount of samples in this file if the data acquisition mode is set to automatic at the Options window. In
case of a manually data acquisition time, the sample rate in the file is related to this data acquisition time. When the
poll times get smaller, more samples will be taken and more values will be put into the file.
Empty cells mean that samples have been missed. Check if the Invalid data indicator on the main
window blinks in case of realtime measurement. In this case, it can be necessary to adjust the realtime
settings in FlowPlot or the realtime poll time in FlowDDE.
