2.6.5 Viewing and/or Analyzing
Measurement Data
Data files are named using the following naming
convention: AE51-SX-XXX-YYYYMMDD, where XXX
is the instrument unique indentifer number. Data
files are formatted such that they can be imported
directly into Microsoft Excel or can be uploaded
®
to the AethLabs website. Please note that when
opening data files in Microsoft Excel , formatting
®
may automatically be changed, making it difficult to
upload to the website.

2.6.6 Data File Structure

The data files are plain text with the extension .dat or .csv. The file consists of a header containing descriptive
information; a line identifying the columns; and then a number of data lines with each item separated by a
semicolon or comma depending on the file format chosen at the time of download.
An example of the header is:
AethLabs
Device ID = AE51-S4-558-1204
Application version = 2.1.0.1
Flow = 100 mlpm
TimeBase = 60 s
Date(yyyy/MM/dd);Time;Ref;Sen;ATN;Flow (ml/min);Temp(C);Status;Battery(%);BC(ng/m
The first line of data does not contain the final BC calculation; all subsequent lines show this expressed in
units of ng/m of BC. A typical excerpt of data lines is shown below:
