Current sensor Sensors measuring current are referred to as “current sensor.”
S/s
The number of times per second the analog input signals are digitized by the
instrument is represented in “samples per second (S/s).”
Example: “20 MS/s” (20 megasamples per second) indicates that the signal is digitized
20 × 10
6
times per second.
Accuracy
We dene 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.
