What is the Data Matrix and how is it used?

The Data Matrix is a data-collection mode in LabQuest (v. 1.5 or newer) and LabQuest 2. It was created to improve data collection in the field by addressing several key issues. These include:

1. Collecting data at multiple locations and over multiple days, all in one file.
2. Collecting data from more sensors than there are ports available.
3. Collecting data from certain combinations of water quality sensors that previously could not be used together due to electrical interference.
