Gen] - Fluke PG9000 Series Operation And Maintenance Manual

If pre-deceleration is OFF and AutoRotate is ON, then piston rotation
deceleration occurs after entry of the pressure or mass target value and only if
the new target requires changing of the main masses with a manual mass set, or
operation of the AMH if an automated mass handling system is active.
 OPERATION
To turn ON and OFF the function that causes stopping of the piston rotation to
initiate when [ENT/SET P] is pressed, press [ROTATE], <2pre-decel>. The
cursor is on the choice corresponding to the current state. Select <2on> for
piston rotation deceleration to initiate when [ENT/SET P] is pressed. Select
<1off> for deceleration to initiate only after entry of a new pressure or mass
target and only if the main masses need to be moved, or if the AMH needs to be
operated. The default is <2on>.

[GEN]

 PURPOSE
To turn ON and OFF automated pressure generation / control, and to view and edit the
automated pressure control settings. Requires that an automated pressure generation /
control component (such as a PPC4) be included in the PG9000 system and properly
configured (see Section 2.4.11).
 PRINCIPLE
PG9000s support automated pressure generation / control components. These components, when
properly configured and interfaced with the PG9000 platform, are controlled by the PG9000
platform to automatically set and adjust pressure to float the piston. Automated pressure
generation and control components are interfaced with the PG9000 platform via the COM3
RS232 port (see Section 3.12.5.1).
Once an automated pressure generation/control component has been configured and
interfaced with the PG9000 platform, the functions under [GEN] are used to turn automated
pressure generation/control ON or OFF and to set operating parameters associated with
automated pressure control.
With automated pressure generation/control ON, PG9000 uses the automated control
component to float and refloat the piston when a pressure or mass value is entered. [SET P /
ENT] is pressed to initiate a new set command.
suspended when any function key is pressed, when entering remote mode or if automated
pressure control is turned OFF.
After a target pressure or target mass has been entered (locally or remotely) and the required
mass has been loaded, the GEN function controls the pressure control component to float the
PG9000 piston to the piston float target (see Section 3.10.9.1) and refloat it when necessary.
If the piston moves beyond the high or low piston position Ready limit the GEN function
refloats it to the piston float target. The piston float target and piston position ready limits are
user adjustable (see Section 3.11.2 and 3.11.3 <6READY>). See Section 3.5, Figure 14 for
a description of the piston position stroke zones and limits.
With automated pressure generation/control OFF, PG9000 leaves the automated pressure
generation/control component idle and does not attempt to use it.
If an automated pressure control component is included in the PG9000 system, automated
pressure generation/control is generally left ON for normal operation. It is turned OFF in
situations where pressure control independent of operator initiative is undesired (e.g. when
performing a crossfloat intercomparison with another piston gauge).
The [GEN] menu includes:
1. Turning the GEN function ON and OFF.
2. The adjustable piston float target that defines the position to which the piston is set
when floated (see Section 3.10.9.1). (e.g. how far above mid float must the piston
be before the float process is considered completed)
3. A choice to have the piston raised to the top of the stroke before manipulating
mass using an AMH (see Section 3.10.9.2).
