8.6.11 Data set DS 76 min. and max. measured values of the frequency and the THD
The table below shows the content of data set 76 in which the minimum and maximum
measured values of the frequency and the THD are transmitted. It also contains the
associated time stamps for these minimum and maximum measured values.
The table below contains the data sets DS76: Min./max. measured values of the
frequency/THD and the associated time stamps (length 92 bytes, read-only):
