Logger Tree

This page is the main working screen of Eclo ExpressThermo. This is where you can review the information collected by loggers that you've just downloaded and also from data files that you open.

You can navigate through the downloaded loggers or the data files using the respective list that is shown at the left hand side (illustration key A). There is a combo box on the top of the list view to choose which of those two lists is visible (illustration key B).

If a logger or data file has an active alarm condition, there will be a visual indication logger alarming next to the logger's ID (illustration key C).
