2.1.4. Vent Mode

WARNING!
Be careful with the pressure connections. High pressures with a large
volume can cause damage to both persons and property.
WARNING!
The calibrator discharges gas to the atmosphere through the supply (-)
and vent ports. Leave these ports free.
The calibrator may produce high sound levels when discharging gas. Use
a muffling device at the vent port.
WARNING!
Before connecting the instrument under test to the output port, make a
VENT operation to discharge any gas inside the controller and go to
MEASURE mode. Before turning the calibrator off, it is recommended to
vent the gas inside the controller.
In this mode, the calibrator turns the pressure control off and vents the pressure
inside the control module through the VENT valve.
