3.1.11 SYSTEM CONTROLLER
The system controller consists of a personal computer, flat panel display, keyboard and pointing
device (“mouse”). These are packed in (2) to (4) corrugated containers, depending on
configuration.
The system controller is delivered with all necessary ADCS-601 system software pre-loaded
including:
- ADCS Tools™
- FPG Tools™
- COMPASS for Pressure™
- USB hub driver
The part number of the system controller is 103388.
3.2 SITE REQUIREMENTS
The environment required to operate an ADCS-601 Air Data Calibration Standard within its estimated
measurement uncertainty limits is generally that of a high level, physical metrology laboratory.
When selecting and preparing a site to set up the ADCS-601 system, the following should be considered:
•
Ambient conditions: To achieve optimum metrological performance, ambient conditions should be
controlled and maintained within the following limits:
•
Temperature: 19 to 23 °C, minimize rate of change of temperature.
•
Relative Humidity: 10 to 60 %RH (non-condensing).
•
Ambient Pressure: Minimize external influences that will cause barometric instability.
•
Air Currents: Do not install the ADCS-601 Reference Bench under a source of vertical air currents such
as an overhead air conditioning or heating ducts. These can exaggerate rate of change of ambient
temperature.
•
Vibration: Minimize local vibration. Excessive vibration will reduce the stability of the pressures
defined by PG7601 and the FPG8601 (vibration affects the floating piston).
•
Overall footprint: The ADCS-601 Control Cabinet and Reference Bench must be disposed as
shown in Figure 1. Select a location where adequate space is available, also consider the location of
the system controller (PC) and connection of a device under test (DUT). See Figure 26 for typical
ADCS-601 system layout at site of use.
•
Access to rear of Control Cabinet and Reference Bench: To perform maintenance functions and
troubleshoot the ADCS-601 system, it is necessary to have access to the rear of the Control Cabinet
and Reference Bench. Be sure the ADCS-601 is installed so that 360 degree access to areas of the
system is available.
•
Electrical power supply: Plan the supply of electrical power to the Control Cabinet. See Section
1.1.1 for electrical power requirements. Note that the vacuum pumps draw a high amount of power,
particularly when starting up.
•
Pressure supplies: Plan the pneumatic pressure supplies to the rear panel of the Control Cabinet.
Two separate supplies are required (see Section 1.1.1). The Test Gas Supply must be very clean
and dry. This gas supplies the PG and FPG piston-cylinders. Cleaner gas will reduce maintenance
by reducing the necessary piston-cylinder cleaning frequency.
•
Bell jar and AMH placement: Plan a location for the PG7601 bell jar and automated mass handler
when they are removed from the platform.
