If cm
2
is used as measurement unit, the set value must be
integer and range from 10 to 100000 cm
2
. If in
2
is used as
measurement unit, the set value must have a decimal digit
after the comma and range from 1.5 to 15500.0 in
2
.
Note
: the value set to in
2
is internally converted into cm
2
,
therefore a deviation of ± 0.1 in
2
between the value set by
the user and the value actually stored may occur, due to the
rounding up of the conversion result.
