4.1.1 Display 1/10 e
The software version and the use ZONE will be displayed (for about two seconds).
The instrument has a device for which the 1/10 division can be displayed as long as the related parameter is
enabled.
Once the terminal has been programmed in this manner, during normal display the last digit on the weight display
(on the right) will remain off.
Pressing and at the same time activates the procedure and the last digit is lit up and is the value of
the 1/10 division.
This display will remain active for about 5 seconds after which the terminal will automatically return to the normal
weight display.

FILENAME : mb02 rev.4 rel 1.16
Through internal programming you can enable the multiple division function in two weight ranges each with a
minimum verification division.
The instrument, whether loading or unloading, automatically updates the verification division to the value related
to the partial weighing range.
The drawing below illustrates the function for a multiple division application in three weight ranges:
0 kg Min2 = Max1 Max2
Resolution e1
Resolution e2
Min = 20 e1
Partial range 1
Partial range 2
Where Max1 =maximum capacity of the partial weight range defined by the division e1. Min1
=minimum capacity of the partial weight range defined by the division e1.
Tare acquisition
When a tare weight is acquired, the weighing always starts from the lower range, that is the one with the lesser
verification division.
A self-weighed tare value can be equal to Maxr minus e1.
Example: 3000 kg scale with two division ranges:
Partial range 1: 0 ÷ 1500 kg e1 = 500 g
Partial range 2: 1500 ÷ 3000 kg e2 = 1000 g
If a tare of 2500 kg is acquired, weighing starts with the division e1 (500 g), with Max1 equal to 1500 kg. Since
the full scale is 3000 kg, in this example, since the first range of 1000 kg is exceeded, only 500 kg remains in
the second range (e2 =1000 g) for arrive at full scale: 3500 kg (tare) + 1500 kg (first range) + 1000 kg (second
range) = 6000 kg.
The situation is illustrated in the figure below.
Tare = 2500 kg
If in multiple divisions the operating range is not signalled by acquiring a tare, it always restarts from the first
weighing range.
Entering tare weight (preset tare)
If a tare is entered, the maximum value of the tare may not be greater than the Max1value, which is the
maximum capacity of the first partial weighing field.

FILENAME : mb02 rev.4 rel 1.16
Through par.18= 003 or 004 you can enable the multiple range weighing function, getting instruments with two
or more distinct scales, each having a range from zero to the maximum capacity. Each scale has its own
verification division and minimum capacity and is a distinct weighing range.
Switching from one weighing range to the next occurs automatically when the load exceeds the maximum
capacity of the lower range. This switching only occurs for increasing loads and the value of the higher division
reached is maintained in discharge until balance is reached with the instrument unloaded (zero). When this
condition is reached (meaning zero) switching occurs of the verification division compared to the minimum
division.
The drawing below illustrates the function for a multiple range weighing application in three weight ranges:
0 kg Max1 Max2= Max
Resolution e1
Resolution e2
Min1
Min2
Range 1
Range 2
Min1 = 20 e1 Min2 = 20 e2
Where Max1 =maximum capacity of the partial weight range defined by the division e1. Min1
=minimum capacity of the partial weight range defined by the division e1.
Acquiring and entering tare (preset tare)
For multiple range weighing instruments there is no limitation on entering the tare as in the multiple division
function. When entering a preset tare weight, upon automatic switching to the higher weighing range the value
is automatically transferred to the higher range and rounded to the value of the new division. The tare value,
which can either be acquired or entered, is equal to Maxr - er.
In multiple range weighing instruments using indication , notification is given of which weighing range
is being used.
