The totalization operation consists of adding the current weight value to the sum of the previous weights and increasing by one the number of weighing operations. To access the list of available totals, follow the pathway:

(Shortcut key TOTALS )

5.3.1 Weighing data reprint

Access the Reprint item of the user menu to obtain the last printout again without having to change the consecutive number and any totals calculated.

The word Copy will appear on the reprint to distinguish it from the original.

5.4.1 Standard operation

In standard operating mode, the terminal can acquire the gross (or net) weight on the scale and display it along with the weighing symbols. In this case, the possible display formats are 15mm digits, 30mm digits and Selection (see par. 5.2.4 ).

5.4.2 Sum weighing operation

The sum weighing operating mode allows you to perform weighing operations in sequence without unloading the scale, zero-setting the net weight after each operation. To move from one weighing operation to the next, press when the weight is stable.

On completion of this operation:

		thenet weight is zero-set and the weight currently on the scale is taken as the tare;
		a string is sent to the serial port or the data is printed (if a printer is connected).

The display formats available in this operating mode are 15mm digits, 30mm digits and Selection (see par. 5.2.4 ).

5.4.3 Loading extraction operation

This operating mode, when selected and associated with the I/O devices, allows you to perform simple dosing operations with a number of different components.

The I/O are selected during the installation phase.

Comply with the instructions in par. 5.2.8 and enter the Set Point 01 and Set Point 02 values. Set Point 01 defines the final weight value to extract, Set Point 02 gives the weight value that, subtracted from the Set Point 01 value, marks the change from fast extraction mode to slow extraction mode.

On pressing the key in correspondence with the indication START , the extracted weight value is zero-set and scale loading is enabled. The display shows the gross weight (the weight on the scale) and the extracted weight (the weight gradually loaded onto the scale).

The display format used in this operating mode is Extraction (see par. 5.2.4 ).

The extraction operation can be concluded by pressing STOP.

5.4.4 Unloading extraction operation

This operating mode is identical to the previous mode except that in this case you start with a loaded scale and gradually remove material.

Enter the Set Point 01 and Set Point 02 values ( par. 5.2.8 ).

On pressing the key in correspondence with the indication START , the extracted weight value is zero-set and scale unloading is enabled. The display shows the gross weight (the weight on the scale) and the extracted weight (the weight unloaded from the scale).

The display format used in this operating mode is Extraction (see par. 5.2.4 ).

The extraction operation can be concluded by pressing STOP.

6.6.1 Memory capacity

The memory capacity of the MPP expansion board is sufficient to store the data for approximately 130,000 weighing operations (weight + 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.

6.6.2 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. 6.6.4 ).

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.

6.6.3 Disabling MPP

It may sometimes occur that you do not wish to transfer the weight data or save it in the MPP memory.

In this case, to disable MPP, type:

...>MENU> MPP operation>De-activated

To subsequently re-enable MPP operation:

...>MENU>MPP operation>with memory

You can also access the MPP operation menu by pressing the shortcut key MPP.

6.6.4 Checking memorised weight data

To check the data saved in memory, press the shortcut key COD MPP.

The terminal displays the net weight and the tare associated with the MPP identification code of the last weighing operation to be performed.

By pressing SETCOD you can call up previous weighing operation data by entering the relative code number (see par. 5.1.2 ).

If the terminal is equipped with a printer, by pressing you can print the weight data displayed and the relative identification code.

The MPP terminal number or serial number may appear in the print heading, depending on the type of response selected during the installation phase.
