Chapter 4 42
In order to optimize the use of the Datalogger in your QH5 U you first
need to understand how data is organized. Up to 8 individual files
with alphanumeric names are used to store data. Each file contains a
grid with columns and rows, and each grid contains columns
identified with consecutive letters (
A, B, …AA, AB… ) that store an N
number of measurements (group). Each value is identified with a
column letter and a row number.
Figure 4.1: Organización de datos
With this grid structure the location of a value is always represented in
a “ Batch, Cell” . For example F,7 means that the value is stored in
column / batch F, row / cell 7.
The number of measurements in a batch is set in
Group (N) so that
every time the batch reaches the N number of values it automatically
closes and a new batch is opened. When the (N) is changed the
number of measurements changes without closing the file which
allows different size batches within a single file.
