If the mass set and PG7000 Platform were delivered together, the mass set
has already been entered at the factory. Before creating a new mass set, check
whether it already exists using the view mass set function (see Section 3.11.1.8).
PRINCIPLE
The PG7000 add and edit mass set functions allow mass set composition and
metrological variable values to be defined and stored. These values will be used
by PG7000 when the mass set is made active to calculate nominal mass
instructions and true mass loads. Up to three mass sets can be created.
Setting up or editing a mass set requires defining the density of the masses, the
mass set composition and the true mass of each individual mass. This
information can be found in the calibration report for the mass set.
Mass sets are created and edited in terms of mass groups reflecting the normal
composition of a PG7000 mass set. Standard PG7000 mass sets are made up
of these groups (see Section 2.1.2.2 for listings of standard PG7000 mass
set compositions).
The mass groups of a
MANUAL
mass set include:
1.
Make
up
mass (9, 4.5 or 4 kg)
: A single mass, sequentially numbered
1
.
The value of this mass is 9 kg if the mass set main masses are 10 kg and
4 kg or 4.5 kg if the mass set main masses are 5 kg. The purpose of this mass
is to arrive at a whole number nominal mass load equal to the sets main
masses (10 kg or 5 kg) when added to the piston and mass loading bell.
2.
10 kg masses
: The main masses in a standard 80 or 100 kg mass set.
Sequentially numbered from
1
up to the total number of 10 kg masses.
Mass sets of < 80 kg do not normally include 10 kg masses.
3.
5 kg masses
: The main masses in any standard mass set of less than
80 kg. Sequentially numbered from
1
up to the total number of 5 kg masses.
Standard 80 and 100 kg mass sets have one 5 kg mass.
4.
2 kg masses
:
Every standard mass set has two 2 kg masses numbered
1
and
2
.
5.
1 kg masses
:
Every standard mass set has one 1 kg mass numbered
1
.
6.
0.5 kg masses
: Every standard mass set has one 0.5 kg mass number
1
.
7.
0.2 kg masses
: Every standard mass set has two 0.2 kg masses numbered
1
and
2
.
8.
0.1 kg masses
: Every standard mass set has one 0.1 kg mass numbered
1
.
9.
Trim
masses
: Every standard mass set has a trim mass set made up of
masses from 50 to 0.01 g. These masses are NOT defined and entered as
part of the mass set.
The mass groups of an
AMH
automated mass handler mass set include:
1.
Main masses (10 kg with AMH-100, 6.2 kg with AMH-38)
: Sequentially
numbered from
1
to a maximum of
9
for AMH-100 or
1
to a maximum of
5
for
AMH-38.
2.
6.4 kg mass (AMH-100 only)
: Single tubular, binary mass.
3.
3.2 kg mass
: Single tubular, binary mass.
4.
1.6 kg mass
: Single tubular, binary mass.
