An ADIDAT file is a data file used by LabChart (version 6.1.1. and later), software used to record and analyze biological signals. It contains raw data, such as heart rate or systolic pressure, saved in the ADInstruments Simple Data file format. ADIDAT files do not include settings.

ADIDAT files are created when a user exports data as "raw data" from LabChart. The file format is only supported by versions 6.1.1 and later. LabChart allows you to connect various devices in order to record, view, analyze, plot, and share biological signals. The program is used for medical purposes, such as calculating a person's cardiac output or analyzing blood pressure. LabChart is used in research and educational fields that include muscle, cardiovascular, respiratory, nervous & sensory, electrophysiology, chemical & physical, and exercise & sport science disciplines.
