DC Measures Settings Menu
5.5.1. Overview
This menu allows calibrating DC current measures (detected with an optional, external current transducer;
see Additional C
omponents for the “Energy Counter” Application) in Menu n.3 – DC Measures.
It can be viewed only if parameter
R023
=
2:XMDO+Pout, or
4:XMDO+PT100+Pout, or
6:XMDO+ADE+PT100+Pout (see the Expansion Board Configuration Menu).
