The REF port can be sealed from atmosphere in most applications where the test
times are relatively short. This isolates the port from pressure changes in the
atmosphere and results in very stable pressure measurement and control.
If the test times are relatively long, in addition to connecting the reference ports
together, also routinely vent the system by placing it in VENT mode. This will
ensure there is no buildup of pressure on the reference port due to temperature
effects.
For Products that have a BRM (Barometric Reference Module) installed, the
barometer is tied to the reference port. When Gauge mode is used, connect the
REF port as noted above. When used in the Absolute mode, if the ambient
pressure is not stable, sealing the reference port from atmosphere improves the
control stability of the Product.
VENT Port
The VENT Port ties the internal volume to atmosphere when the Product is
vented.
Note
Leave the VENT port open to atmosphere to ensure proper
operation of the Product.
