times per second.
Accuracy
We dene measurement tolerances in terms of f.s. (full scale) and rdg. (reading) values, with the
following meanings:
f.s.
(maximum display value or scale length)
The maximum displayable value or scale length.
rdg.
(displayed value)
The value currently being measured and displayed on the measuring instrument.
setting
(setting value)
Indicates the value set as the output voltage, current, or other quantity.
