measurement speed

The measuring speed indicates how many measurements can be performed in a unit of time. It depends on various factors and on whether the measurement is made with a pointer instrument or with a digital instrument.

In general, a new measurement can only be performed when the previous one has been completely finished, which means that the pointer of a pointer instrument or the digital display of a digital instrument must first have adjusted to the measured value. The complete measuring cycle is only completed when the measured value display is in the rest position again. This time period is considerably affected by charging and discharging processes. The time for such a measuring cycle is the measuring time. The reciprocal of the measuring time is the measuring rate. For example, if the measurement time is 0.5 s, then the measurement rate is two measurements per second.

With digital instruments, the measurement time is essentially determined by the resolution and the A/D conversion used. An increase in resolution by a factor of ten can be accompanied by a reduction in the measurement speed by the same factor.
