6.1.3.5 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 with a multiple pin connector
present in Pascal ET front panel. This module is plug-and-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.
Environmental parameters module with range and their resolutions are in the table, see chapter 3.9 "Environmental
parameters module".
