If the device is provided with analog outputs allocated to certain measured values dur-
ing the configuration according to Section 5.1, they can be read out in the display (e.g.
analog instrument).
Except for the current measured values the user can also read out the minimum, max-
imum and long-term measured values. The interval range for the calculation of the av-
erage value was set in Subsection 6.23.4.
The following average values are available:

• Qdmd, QdmdForw, QdmdRev: the reactive power as a whole and separately ac-
cording to Demand Forward and Demand Reverse;
• Sdmd: the apparent power.
