6.1.2.5 Environmental parameters module (optional)
This module allows to measure: temperature, relative humidity and atmospheric pressure. These
parameters represent the most important factors that affect the calibration results. This module is
connected to Pascal ET or Pascal ET/IS with a multiple pin connector present on the right side
panel. This module is plug & play and the relevant information about the environmental parameters
are displayed on the status bar at the top of the screen.
This information is automatically reported on the calibration report.
