under, the other case(s) contain(s) the main masses of 10 or 5 kg each. Each mass
is packed in a sealed plastic bag and then placed in a protective shipping insert.
The stability over time of PG7000 pressure measurements is a function of the
stability of the masses loaded on the piston. Precautions should be taken in
handling the masses to minimize influences that may change their mass. This
includes always wearing protective gloves when handling the masses to avoid
contaminating them with body oils and perspiration. Protective gloves are provided
in the accessory kits of PG7000 Platforms.
To install the masses on the mass loading tray, proceed as follows:
Open the shipping cases.
Install
the
main masses:
The
main
masses (a series of 10 kg masses if the
mass set is > 55 kg, a series of 5 kg masses if the mass set is < 60 kg)
are installed horizontally aligned on the mass loading spindle.
The
main
masses are sequentially numbered starting with he number
1
.
The
main
mass with the
highest
sequential number is installed first at the
bottom of the stack (i.e., the first mass loaded on the tray). The rest of the
main
masses should be stacked
upwards in descending
order ending with
main
mass sequential number
1
. Be careful NOT to confuse the
makeup
mass (refer to next item) with
main
mass
1
.
Install the make up mass:
The
make up
mass is a single mass
sequentially numbered
1
. It has the same diameter as the
main
masses. It
is a 9 kg mass if the
main
masses are 10 kg. It is 4 or 4.5 kg if the
main
masses are 5 kg.
The
make up
mass is placed on top of the
main
mass stack. It is always the
top of the stack.
Install the fractionary masses:
The
fractionary
masses are all the masses
of lower value than the
main
masses and
makeup
mass. These are masses
of 5 kg and under for mass sets with 10 kg
main
masses. They are masses
of 2 kg and under for mass sets with 5 kg
main
masses.
Fractionary
masses
of 1 to 5 kg are discs with a central hole.
Fractionary
masses of 100 to 500 g
are solid, small diameter pucks.
Fractionary
masses of 50 g and under are
grams masses packed and stored in their own separate storage case.
Fractionary
mass discs and pucks are installed vertically in the corresponding slots
in the mass loading tray. Use a consistent setup for the sequence number
when there are two masses (e.g., always load sequential number
1
in the front).
2.3.2
INSTALLING A PISTON-CYLINDER MODULE INTO THE
PLATFORM
To operate the PG7000 Platform, a piston-cylinder module must be installed in its mounting
post. To install a piston-cylinder module in the PG7000 Platform, proceed as follows:
Remove the PG7000 Platform mounting post plug.
Unscrew the ORANGE plastic
mounting post plug that is installed in the PG7000 Platform mounting post.
Rotate counterclockwise to remove.
Remove the piston-cylinder module from its bullet case.
Select a piston-cylinder
module. Open the piston-cylinder module bullet case by rotating its lid counterclockwise.
Remove the piston-cylinder module from the bullet case base by unthreading it from the
case. Hold the piston-cylinder module body by the knurled area and rotate it
counterclockwise.
