Once logging has begun and immediately after it stops, you can view metadata about the
logging session (how many points of which parameter(s) were captured at a particular
sampling rate) on the LOGGER Status bar near the top of the program.
As noted above, in all modes except Real-time you must take a separate step to download
logs saved in the meter to your PC. Pressing the virtual Download button stops recording
in all modes. If you exit the program before saved logs have been downloaded , the logs
will be erased from the meter's memory. In Key Start and Rollover modes, saved data must
be downloaded before another logging session can be initiated.
The progress of the downloading process is shown on the blue Alert bar at the bottom of
the program. It's important to mention that downloading data to a PC is not the same as
saving it there. A message on the Alert bar such as "Reminder: Data is not stored!" should
prompt you to manually save downloaded data by left-clicking the File pulldown at the
upper left of the program, navigating down to the Save File line, and left-clicking again.
This will save the data logs as an ASCII file in .csv format in any directory (folder) of your
computer that you choose. The message "Save file completed" on the Alert bar will confirm
the transfer.
Once a file has been saved, you can use various tools of the data logging program to view,
manipulate, modify or print its content. Among the most useful of these tools are the Data
Table line under the View pulldown and three graph manipulation tools. Clicking on View
Data Table converts a data log
graph to a table that may allow
easier viewing of individual
date/time-stamped readings.
The three graph manipulation tools
allow you to use your computer
keyboard to zoom in and out on a
section of a data log plot, move the
plot left or right to focus on a
particular time period, and present
a set of readings taken at a particular time
on the three colored windows (for Temp,
Humidity and VOC) above the Alert bar.
In the explanatory schematic shown at right,
the dark quarter-circles within the ovals
labeled Mouse represent the mouse's left
and right buttons.
