7. OPTIONS
7.1 MPP memory expansion boards
Terminals provided with the MPP option (permanent weight memory) can memorise the weight data
of each individual weighing operation in a permanent memory and transmit the value to an external
peripheral along with an identifying code ascribed by the terminal itself.
It is possible to check whether the data item is correct by entering the identification code in the
weighing terminal. The identification number comprises 7 digits, which means that the number will be
repeated after 10.000.000 weighing operations.
7.1.1 Memory capacity
The memory capacity of the MPP expansion board is sufficient to store the data for approximately
130,000 weighing operations ( tare), which corresponds to around 8 months of continuous
use of the terminal, performing 500 weighing operations per day.
If the terminal is used less frequently, this period will be extended.
CAUTION
The memory recovery operation may require a few minutes during which time the terminal cannot
be operated. Do not switch off the terminal during this operation as this could result in the loss of
the data in memory.
7.1.2 Operation
The type of MPP operation is defined during installation.
There are two main types of operating mode (for further details see the advanced user manual):

in the first type, the user operates from the terminal by pressing to save and transfer the
weight data;

in the second type, the user works from the PC keyboard in the way determined by the specific
software.
In both operating modes, on completion of the saving operation, the user can display the progressive
number associated with the weighing operation (see
par. 7.1.4 on page 1-93 ).
Code MPP will only appear on the display when the memorising operation is enabled with the key.
Both the weighing terminal and the PC may signal errors caused by failure to transfer or save the
data correctly. In this event, follow the on-screen instructions.
