7.3.3.2 UPDATING MASS SET CALIBRATION INFORMATION
Mass set information is element specific metrological data. Uninformed or
accidental altering of this information may lead to out of tolerance
measurements. Mass set information should only be edited by qualified
personnel as part of the ADCS-601 calibration or recalibration process.
When a mass set is recalibrated, the results are given in a calibration report.
The calibration report lists a value measured by the calibration facility for each
mass. These values may change from calibration to calibration and the new
values must be entered into the ADCS-601 system so that they are used in its
pressure calculations. For additional information on PG7601’s AMH-38 mass set
characteristics and how they are stored in the PG7601 platform, see the PG7000
Operation and Maintenance Manual.
ADCS Tools has the capability to to view or edit the value of the PG7601’s AMH-
38 mass set masses. Use [Maintenance], [Calibration], [Mass Set[ (see
Figure 64). The mass set calibration data is displayed and edited in the [Mass
Bell] and [Mass Set] panels.
The mass set and mass bell shown are always the
ADCS-601 PG7601’s active mass bell and mass set. Check that the correct bell
and mass set are shown by verifying their serial numbers against the serial
numbers shown in the panel labels. To change the active mass bell and mass
set use [Setup], [Configuration], [PG].
To edit the mass bell value: click on the value and enter the desired value. Be
sure to enter the value in kilogram. The average density value is a constant that
does not change with calibration. It is reported with the mass set’s original
calibration report. This value is different from the density value for the rest of the
mass set because the mass bell is the assembly of the bell, binary mass tray and
mass lifting shaft and some of these parts are made of titanium.
To edit the value of the masses in the mass set: click on each value and enter
the desired value. Be sure to enter the value in kilogram. The density value is a
constant that does not change with calibration. It is reported with the mass set’s
original calibration report.
When all changes are complete, press the [Save Changes] button to cause ADCS
Tools to store the entered values permanently in PG7601 Platform memory.
Use [Close] to leave the form without making any changes.
Use [Reload] to reload the form with the values that are in the PG7601 Platform
memory. This feature can be used to verify the data entered after [Save
Changes] has been pressed.
