INFOBEREICH
Die Angabe „MatNr/Version/Datum“ bzw. „1234560000/00/MM.YY“ ist als Textvariable deniert
und kann nur auf der „Rueckseite“ editiert werden. Die Textvariable erscheint in allen Doku-
menten dieses Buches, sobald eine Synchronisierung des gesamten Buches(!) durchgeführt
wird. ACHTUNG Die „Rueckseite” muss als Formatquelle(!) ausgewählt sein!
4.3.3.4 Parameter list
• The parameter list is a list of addresses for settings that can be directly implemented on Energy Analyser
D550.
• The parameter list forms part of the installation instructions.
If the Energy Analyser D550 is in “Programming mode” you can edit the values in the parameter list with nu-
meric 1 and 2 keys (see Manual).

4.3.4 Measurement
4.3.4.1 Measurement values
• A measurement value (in the Energy Analyser D550) is an effective value generated over a 200 ms pe-
riod (measurement window).
• A measurement window has 10 periods in the 50 Hz network and 12 periods in the 60 Hz network.
• A measurement window has a starting point and an end point.
• There are approx. 2 ns between the starting point and end point.
• The precision of the starting and end points depends on the precision of the internal clock. (Typically
+-1 minute/month)
• Comparing and aligning the time in the device with that of a time server is recommended in order to im-
prove the internal clock’s precision (time).
4.3.4.2 Full wave effective values
• A full wave effective value is a measurement value that corresponds with the formation of a full wave
over a measurement period.
• For full wave effective values, measurement results are generated every 20 ms (50 Hz) or every 16.7 Hz
(60 Hz).
• Full wave effective values can be used in Jasic programs.
• Calculated full wave effective values
