The structure and significance of meter type designations are described in
section 2.4 "Type designation". The following conventions are employed in
this user manual for representing type designations:

The lower case letter "x" can be used as an unknown to indicate
different versions (e.g. ZxD400 for the ZMD400 and ZFD400 meters or
ZMD410xT for the ZMD410AT and ZMD410CT meters).

The digit pair "00" can be used to indicate accuracy data (e.g. ZxD400
for the ZxD405 and ZxD410 meters).

The abbreviated type designation ZMD or ZFD meters can be used
when all three-phase four-wire meters or three-phase three-wire meters
are meant.

The following collective terms are also sometimes used instead of the
type designation:
– "Active energy meters" for the E650 ZxD400AT meters
– "Combimeters" for the E650 ZxD400CT meters
