Vent Mode
Vent mode vents the pneumatic system and shuts off the supply. The Vent mode can be activated
from the Measure or Control mode by pressing the [Vent] button. Internal system pressure will be
vented through the Vent port.
Figure 7-20 Vent Mode
WARNING
Venting will cause a sudden loss of pressure in the system and the plumbing
connected to the measure control port. Care must be taken that the device under test
is not damaged during venting.
WARNING
In some cases venting will exhaust high velocity air from the vent port. Personnel and
sensitive equipment should not be in close proximity to the vent port during venting.
WARNING
In some cases venting high pressure will cause a loud sound. Personnel should wear
a hearing protection device when working with high pressures.
The figure below shows the state of the isolation valves in Vent mode.
