3.8 Reading out electrical
measured variables
EIB Delta-Meter
Electricity Meters
The measured variables are measured again approx. every 5 seconds and
can either be read out in 'Instrument mode' or in Menu mode [4 InStr].
In the case of transformer rated meters all measured variables are
secondary values.
The measuring accuracy of all the values corresponds to the requirements of
the norm IEC 1036 within the supply voltage tolerance of ± 20 % and the
current range of 0.05 I

Up to 24 electrical measured variables can be displayed in Menu mode
[4 InStr], depending on the EIB Delta-Meter. All electrical measured
variables are secondary values.
