kkk.k

must be expressed and loaded following the mass loading rules below:
Mass Loading Rules
See Sections 2.3.1.3, Installing Masses On The Mass Loading Tray and 3.6. for PG7000 mass set principles
and protocol information. Refer to display examples immediately above to identify
kkk.k
and
gg.gg
.
See
EXAMPLES: Mass Loading
below for mass loading examples.
PG7000 mass loading entries and instructions are always formatted:
kkk.k kg and nn.nn g
•
The mass set being used must be selected as the active mass set (see Section 3.11.1.10) and must
be properly set up prior to use (see Section 3.11.1.6).
•
kkk.k is made up of the piston, the mass loading bell and mass set masses of 0.1 kg and greater.
When using an AMH mass set, the binary mass carrier and mass lifting shaft are also included.
•
kkk.k always includes the mass loading bell and then the makeup mass, if possible.
•
kkk.k is made up of the largest masses possible rather than a combination of smaller masses.
EXAMPLE: To load 5 kg on a PG7601:
USE the piston (0.2 kg) + the mass loading bell (0.3 kg) + the 4.5 kg makeup mass.
DO NOT USE the the mass loading bell + 2 kg #1 + 2 kg #2 + 0.5 kg #1.
When several masses of the same nominal value are included in
kkk.k
, they are loaded in numerical
sequence, low to high.
EXAMPLE: When loading three 5 kg masses:
USE 5 kg mass #1, #2 and #3.
DO NOT USE 5 kg mass #4, #3, #1.
This rule will be followed automatically if masses are installed and used as described in Section 3.6.
•
gg.gg
is made up of mass from the gram trim mass set (masses of 50 g to 0.01 g). These masses
can be loaded in any order.
When PG7000 provides mass loading instructions and calculates the true mass of the mass currently
loaded, it assumes that the mass set in use has been set up correctly (see Section 2.3.1.3).
For PG7000 mass loading protocol to operate properly, the mass set in use must be EXACTLY the mass set
that has been defined by the add and/or edit mass function (see Section 3.11.1.6).
