1Introduction
This users’ manual is to provide necessary information to the users of 6t Mass Properties

Measuring Facility (referred to as “this facility” hereafter) located in Spacecraft Integration and Test
Building.
This facility is used to measure the mass of a test specimen (■abbreviated as TS hereafter) forsystem tests, e. g., “development test”, “qualification test”, “proto flight test”, “acceptance test”, etc.

2Brief Overview of this Facility

2.1 System Outline
This facility is made up of a mass measuring system which measures the mass of a TS, and amass properties measuring system which measures the center of gravity (■abbreviated as CGhereafter) and the inertia moment of a TS.

Figure 2-1 System Outline of 6t Mass Properties Measuring Facility(1) Mass measuring system
This system is used to hang a TS by a crane with a load cell in between whose output iscalculated to obtain the mass of the TS. Furthermore, accurate mass measurement can beachieved by calculating the correction factor using a calibration weight that has the mass ofapproximately around the predicted mass before performing measurement. Also, the mass ofa TS weighing 150 kg or less can be accurately measured using the large precision platform
scale which belongs to the system.
The system is made up of the following items.
(a) Mass measuring load cell

3Users’ I/F

3.1 Test Configuration(1) Location of this facility
This facility is located in the properties test room where the 10-m alignment measuring
facility is also located.
A TS is carried in from the shutters on the satellite path side of the properties test room,and placed on the turn table using an overhead crane.
(2) Crane
The specifications of the crane in the properties test room are shown below.
