Accuracy
Hioki expresses accuracy as error limit values specied in terms of
percentages relative to reading and full scale, and digits.
Reading
(Displayed value)
Refers to the displayed value of the measuring instrument.
The limit values of reading errors are expressed in percent
of reading (% of reading, % rdg).
Full scale
(Maximum displayable value)
Refers to the maximum displayable value of each
measurement range. The instrument has measurement
ranges whose values are equal to the maximum displayable
values. The limit values of full-scale errors are expressed in
percent of full scale (% of full scale, % f.s.).
Digits
(Resolution)
Refers to the smallest change in the indication on the digital
measuring instrument, i.e., the numeral one in the rightmost
place. The limit values of digit errors are expressed in terms
of digits (dgt).
