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, ET-P, ET/IS, ET-P/IS with a multiple pin connector present in Pascal ET,
ET-P, ET/IS, ET-P/IS front 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.

6.2 Electrical
The Pascal ET, ET-P, ET/IS, ET-P/IS are multifunction calibrators.
The electrical modules can be maximum four, two of them are input modules (IN A
– IN B), and the
other two are output modules (OUT A
– OUT B).
