To edit the effective area value: click on the value and enter the desired value.
Be sure to enter the value of effective area at 20 ºC in mm

.
To edit the mass 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 piston-cylinder module’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.

7.3.3 PG7601, CALIBRATION OF MASS SET
7.3.3.1 PREPARING FOR CALIBRATION
Piston gauge mass sets are often calibrated in a facility other than that in which
the ADCS-601 system is used so calibrating the mass set requires removing it
from the PG7601 Platform and shipping it. If the mass set and the piston-
cylinder module are to be calibrated by the same facility, they are usually
shipped together, with the PG7601 Platform if necessary.
To ship the PG7601’s AMH-38 mass set it must be removed from the PG7601
platform. See Section 6.5.2 for instructions on removing the mass set from the
platform.
Once the mases have been removed from the PG7601 platform, they should be
packed in protective bags in the molded transit cases in which they were delivered.
Be sure to include the mass loading bell, the binary mass tray and the mass lifting
shaft as they are part of the mass set.
If the complete PG7601 system must be shipped, use the information in Section
3.1 to pack it.
