MT = 2 * AC * APER + (2 * AC - 1) * 100
with:
MT: overall measurement time
AC: average count
APER: aperture time
100 μs is the time for switching the chopper phase.
Using
surement as follows:
●
Chopper is disabled.
●
Average count is set to 1, no matter which average count you have set.
Thus, the overall measurement time is only defined by the aperture time, and the mea-
surement time for a fast measurement is calculated as follows:
MT = APER
The fast measurement setting delivers up to 100 000 measurements per second with-
out any blind time over randomly long time periods. Programming examples are given
in Chapter 9.2, "Performing the Fastest Measurement in Continuous Average
on page 120.
