5-3. Units

The most common unit of weight  used around the world is the gram, but there is often
a need to shift to alternative units specific to the country  where the balance is used or
to select modes such as counting or percent.
The units and the order they appear in the display are as follows:

Among  the units,  those available for  the user  have been set at  the  factory before
shipping.
The unit can be selected in  the function setting mode.  The order of the units available
is the same as above, while skipping the units that are not available.
Some units are not available for higher or lower capacity models. For details, see “13.
SPECIFICATIONS”

Note

It is possible to store only the units that will be actually used from
the units available. It is also possible to specify the display unit that
will be shown first when the power is switched ON. For details, see
“8-4. Storin g weighing units”.
