In order to optimize the use of the Datalogger in your QH5 it is
important that you understand how data is organized.
In the QH5 data is stored in 8 individual files with alphanumeric names.
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 values or measurements (group). Each
value is identified with a column letter and a row number.
Figure 4.1: How data is organized in the Datalogger
In the above grid structure individual values are stored in a “Column
(Batch), Row (Cell)”. So for example C,4: 764 HL means this value is
located in Column C and Row 4.
Column or Batch sizes can be set in the number of Group (N) values
(
Page 36
) so that each time this “N” number is reached, a batch is
closed and a new one is automatically opened. Every time the Group
(N) number is changed, the number of values in each batch also
changes without closing the file. This allows you to have different size
batches within the same file.
