4.3.3 Data Memory Group
The data memory group is used to extract and preview measurement data.
The "Mem Used" section provides a bar graph of the measurement memory usage within the connected uDL1. The
larger the bar graph, the more memory that is used in the device. The color of the bar graph changes from blue to red as
the memory fills.
The "Extract To Master Data File" button allows extraction of the measurement data from the uDL1 into a CSV file.
Prior to clicking this button, ensure that the desired time format is selected. Data may be extracted in UTC (GMT) time,
or in local time. Local time is based on the time zone selected in the operating system of the computer being used to
extract the data. When the "Extract To Master Data File" button is clicked the following save as screen will prompt the
user for the storage filename.
Figure 16 Extract To Master Data File Dialog
The stored file is saved in a comma separated value (CSV) format that can be imported into spreadsheets (i.e. Excel)
and other applications that support CSV import. Note that older versions of Excel support a maximum of 65,000 lines
so large measurement files may not be completely displayed when using those Excel versions. Excel versions prior to
and including version 2003 will have this limitation.
The CSV file is arranged as indicated in the following Excel screen capture. The first line contains header information
which identifies the contents of each column. Each row contains a time stamped event which can include cable insertion
(unit turned on), cable removal (unit turned off), device battery voltage level, GPS Location (in GPS equipped devices),
number of GPS satellites (in GPS equipped units), DC reading, AC reading, device temperature, user notes, and time-
base lock status.
