Input types and ranges
(p.13-12)).
Judgment of over-range: Below −10 % or above 110 % of the range
Decimal point position: 0 to 4 digits after the decimal point are displayed. Values
are displayed so that the entire value does not exceed 5
digits. (Note: Effective resolution depends on the range.)
