Setup; Preparing For Operation - Fluke PG9000 Series Operation And Maintenance Manual

Do not operate the AMH with drive pressure lower than 275 kPa (40 psi).
Damage to the AMH could result.
Vacuum supply
o
in the vacuum chamber (absolute by vacuum mode PG9000 operation). The vacuum supply
assures that the binary mass selection pins remain in the correct position and evacuates
internal AMH volumes to minimize the likelihood of leaks into the reference vacuum.
The vacuum pump for the pressure controller of the PG9000 system can be used for the
AMH vacuum supply
Vacuum drive requirements:
Flow rate: Very low, avoid restrictions or excessive length of connecting tubing
Vacuum pressure:
When using a PG9000 in "absolute by vacuum" mode, do not operate the
AMH without having a vacuum supply connected to the AMH Vent. Always
check that the AMH is supplied with vacuum BEFORE establishing
reference vacuum in the AMH bell jar. Failure to do so may result in
damage to the binary mass pins and/or binary masses.
Do not plug the AMH vent connection. Use only a "SESO" type quick-
connector stem. Plugging the AMH vent connection will prevent the mass
pins from retracting, leading to serious damage to the AMH internal
components.

Preparing for Operation

Before setting up the PG9000 system, see Section 2.2 for information on
site requirements.
To prepare PG9000 for operation:
 Set up the PG9000 Platform (see Section 2.3.1.1).
 Make the system pressure interconnections (see Section 2.3.1.2).
 If a manual mass set is being used, set up the manual mass set (see Section 2.3.1.3).
 If an optional AMH is being used, set it up with its mass set (see Sections 2.3.1.5 and
2.3.1.4).
 If the PG9000 is to be used with a vacuum reference, set up the optional vacuum
reference hardware (see Section 2.3.1.5).
 Caution
: The vacuum supply is necessary for AMH operation when there is vacuum
At least 50 kPa (7.5 psi) under atmosphere
