Load the nominal mass value following the protocol described in Section 3.6 and
press
[ENT / SET P] . When [ENT / SET P] is pressed confirming that the
nominal mass value has been loaded, operation returns to the previous run
screen with the new pressure target and mass value active.

Caution
To make “in tolerance” measurements, it is imperative that all
mass loading instructions be executed following the protocol
describe in Section 3.6. This ensures that the actual mass value
resulting from a nominal mass loading command will be
correct. Failure to load masses following the PG9000 mass
loading protocol is likely to result in out of tolerance mass load
determinations and pressure definitions.
Note
•
The resolution with which the pressure-to-mass mode mass
loading instruction is given depends on the resolution set in
the RES function. The RES function makes it possible to
avoid loading high resolution mass values when it is not
imperative that the pressure defined be exactly the nominal
pressure requested (see Section 3.10.10).
•
The pressure-to-mass loading instruction is given in
nominal mass while the main run screen displays the true
mass loaded. For this reason, the nominal mass loading
instruction and the true mass displayed in the main run screen
are slightly different values. This is normal operation (see
Section 3.6).
3.10.11.2 [ENT / SET P] In Mass-to-Pressure mode

PURPOSE
To set a target mass load (see Section 3.10.12).

OPERATION
Put the PG9000 in mass-to-pressure operation mode (see Section 3.10.12), then
press [ENT / SET P] in any run screen. If automated rotation is on, the
<DECELERATING> screen shows until piston deceleration is complete.
Note
Pressing [ENT] in the run screen causes automated pressure
generation to be suspended if ON and AutoRotate to stop piston
rotation if ON. When [ENT] is pressed to confirm mass entry,
automated pressure generation and/or motorized rotation resume.
The display is:
1. Edit field for total trim mass currently loaded.
2. Edit field for nominal mass of main and
fractional masses currently loaded.
Nominal mass load:
10.0 kg and 3.17 g
Use the numerical and editing keys to enter the nominal mass to be loaded on
the piston following the mass loading protocol described in Section 3.6.
Press
[ENT / SET P] to move from the “kg” entry to the “g” entry, and press [ENT
/ SET P] again to process the mass value. If the mass value entered cannot be
executed, an explanatory error message is displayed momentarily and operation
returns to the mass entry screen with the previous nominal mass value
displayed. If the mass value entered is valid, the value is processed and
operation proceeds to the previous run screen with the new mass value active.
