Figure 28. Activating the Pressure Control Bias
3.
With
Oil Reservoir Valve
closed, and the
Oil Isolation Valve
in Equalize, rotate
the hand pump clockwise to generate the desired line pressure. If barometric line
pressure is desired then do not rotate the hand pump.
4.
When the thermal effect caused by the line pressure change has subsided and the
Tared Reading in the Deadweight Controller screen has stabilized, then press
. The Tared Reading should be zero. Zero Differential pressure is
now applied to the test item.
5.
Set the
Oil Isolation Valve
to Isolate, apply weights corresponding to the desired
differential pressure, and press
. When the control system regulates
the differential pressure for a Tared Reading of zero, then the desired differential
pressure is applied to the DUT.
W
Caution
Turning the hand pump can generate large differential
pressures when the Oil Isolation Valve is in the Isolate position.
Note
If the desired differential pressure requires an increment smaller than that
available in the mass set, then use the
to adjust the Setpoint value. The
desired differential pressure is achieved when the Tared reading stabilizes
to the Setpoint value. When finished with this pressure point, in order to
obtain the next nominal differential pressure, use
to zero setpoint.
