Introduction
Accuracy labeling
The instrument accuracy’s is expressed by dening a percentage of the reading, a percentage
of full scale, and limit value for errors in terms of digits.
Reading
(displayed value)
Indicates the value displayed by the instrument. Limit values for reading errors
are expressed as a percentage of the reading (“% of reading” or “% rdg”).
Full scale
(maximum display value)
Indicates the maximum display value for each measurement range.
Measurement range values for the instrument indicates that maximum display
value. Limit values for full-scale errors are expressed as a percentage of full
scale (“% of full scale” or “% f.s.”).
Digit
(resolution)
Indicates the minimum display unit (in other words, the smallest digit that can
have a value of 1) for a digital measuring instrument. Limit values for digit errors
are expressed using digits (“digits” or “dgt”).
Screen display
The instrument screen displays the alphanumeric characters as follows.
