DATA LOGGER BASICS
• A Time-Line is displayed at the bottom of the screen, that measures the selected
recording time with respect to the elapsed time from the start of the recording event.
In the event that a cursor is also selected, a “time” window appears beneath the cursor,
indicating when that event took place, as measured from the start of the recording event.
When the cursor is de-selected, the “time” window disappears.
• A selected Recording Time window is displayed in the bottom right hand corner of the
screen, which displays the total length of the Recording Time selected.
• The program uses the units information contained in each data bit on the manifold and
displays these units on the main screen and/or the analog screen as required.
• The Data Logger will display NaN or 0 when no value is displayed. (NaN stands for “Not a
Number”). Data points that are NaN or 0 do not appear on a plot, but are present
nonetheless. Periods of time in a plot where there is no value displayed will show up as
a gap in the plot.
