ZME Function
If electrical current or voltage converters are connected to the measurement inputs, the
effective value is measured (throughout the integration time interval), and furthermore
outputted as DC signal (0 – 10V) to the three analog outputs (see also chapter 4.5.4.4, page
21 for this). Additionally, the measurement values are also internally available, and may be
queried via a PC or bus system.
For electrical current converters, the load resistance must also be connected externally, and
the voltage converters must be configured accordingly (see also chapter 4.5.4.8 page 24 for
this). Generally, the output value can be freely adjusted at each of the six analog outputs; for
standard settings the measurement value 1 is read out to output 1, the measurement value 2
is read out to output 2, and the measurement value 3 is read out to output 3. A change of
standard settings can only be performed via a PC program or via a bus system (see also
chapter 4.5.4.4 page 21 for this).
The following figure displays the principle structure and the connection diagram upon use of
the ZME function.
