GENERAL OPERATING PRINCIPLES
4.1.1
SYSTEM CONFIGURATION
The ADCS-601-AF system is completely configured from a hardware and software standpoint
when it is delivered. All necessary operating values are entered into individual components and
all interfaces are set for internal consistency and to communicate with
ADCS Tools
software.
The system hardware configuration can be viewed and edited using panels
[Setup]
,
[Configuration]
form. Changes to the configuration should only be made when necessary
by personnel with advanced knowledge of the system. Uninformed changes to the
configuration are likely to cause ADCS-601-AF to no longer operate properly.
4.1.2
READY/NOT READY INDICATIONS
4.1.2.1
OVERVIEW
Typcial ADCS-601-AF operation consists of using the system to set values of
pressure with very low measurement uncertainty. A variety of operations by the
ADCS-601-AF system may be required to achieve the requested pressure and
the time required to complete these may vary. In order to make it clear to the
operator when a pressure setting request has been completed and conditions
are appropriate for the ADCS-601-AF pressure definition to be within the
estimated measurement uncertainty budget, ADCS-601-AF provides a “go/no go”
Ready/Not Ready
indication.
The
Ready/Not Ready
indication is provided by the
ADCS Tools
software that
manages the overall system (see Section 4.3). The indication is by a circle to the
left of the current pressure reading which is RED when the pressure is
Not
Ready
and
Green
when the pressure is
Ready
.
The conditions that must be met to reach a
Ready
condition vary depending upon
whether the active pressure standard is the PG7601 piston gauge or the FPG8601
force balanced piston gauge. See Sections 4.1.2.2 and 4.1.2.3 for additional
information on the
Ready/Not Ready
criteria for the two pressure standards.
4.1.2.2
READY/NOT READY WHEN USING THE PG7601 PISTON
GAUGE
ADCS-601-AF
uses
the
Ready/Not Ready
directly from the PG7601 to
determine the
Ready/Not Ready
condition. See the PG7000 Operation and
Maintenance manual for a more detailed description of PG7000
Ready/Not
Ready
operation.
When the PG7601 is the active pressure standard ADCS-601-AF pressure
Ready/Not Ready
depends directly upon the PG7601
Ready/Not Ready
condition.
The PG7601
Ready/Not Ready
condition is dependent upon three criteria. For
the PG7601 pressure to be considered
Ready
, all three crteria must be met.
