Caution
Be sure the TEST BYPASS valve is in the OPEN position before
adjusting the static pressure. Failure to do so will cause
differential pressure to be generated across the HIGH and LOW
TEST ports which may overpressure the DUT.
When the static pressure, as indicated
by the RPM, has been set to the desired
value, press
[ENT] . PG9000 reads the
RPM and calculates the mass to load on
PG9000 to set the pressure value
indicated by the RPM. The display is:
Load mass & vac:
9.2 kg & 32.47 g
Note
When using an AMH, the mass value to set the value indicated
by the RPM is always loaded with resolution of 0.1 kg. This is to
avoid having to break the reference vacuum to load trim
masses. The differential pressure values are loaded with the
resolution specified in [RES] (see Section 3.10.10).
This is the standard nominal mass loading in instruction display of pressure-to-mass
mode (see Section 3.10.11.1). The mass loading instruction is always given with
0.01 g resolution regardless of the current mass loading resolution setting (see
Section 3.10.10). Load the mass value following PG9000 mass loading protocol
(see Section 3.6). If an AMH is being used, the mass is loaded automatically and
default mass loading resolution of 0.1 kg is used.
Set the PG9000 Differential Mode Controller (see Figure 19) to apply the
pressure defined by the PG9000 to the RPM (see Table 14).
