Accuracy
We dene measurement tolerances in terms of rdg. (reading)
and dgt. (digit) values, with the following meanings:
rdg.
(reading or
displayed value)
The value currently being measured and
indicated on the measuring instrument.
dgt.
(resolution)
The smallest displayable unit on a digital
measuring instrument, i.e., the input
value that causes the digital display to
show a “1” as the least-signicant digit.
