Operation
This section explains the pressure control settings of the Product.
Pressure Control Settings
The product has these operating modes to control pressure: Control, Measure,
and Vent.
Control Mode – When in Control mode, the Product actively controls pressure
as defined by the Setpoint and will keep the pressure near the Setpoint per the
active control mode. See the Control Modes section. Control is the only mode
where the Product actively controls pressure. The setpoint value can be changed
in any of the three modes, but the Product is idle until is pushed.
Vent Mode – When in Vent mode, all pressure on the test port is vented to
atmosphere.
Measure Mode – When in Measure mode, the Product is holding pressure and
pressure control is idle. This mode provides a method to take a measurement
without control noise.
