The LCD (liquid crystal display) is provided with background lighting for
easier reading.
When a Display Check is made, all segments of the display are illuminated
as shown.

1 Energy direction indicator
P = Active energy (A)
+ = import
2 Phase voltage display (flashes if phase sequence is reversed)
3 Battery low indicator
4 Unit field (W, var, VA, k..., M..., ...h, V, A, h, Hz)
5 Index field (8 digits). A code identifying the values in the value field.
The code is according to the Object Identification System, described
below
6 Arrow symbols for status information according to face plate
7 Value field (8 digits)
The B:C.D.E.F structure applies to Object Identification System (OBIS)
B Defines the channel number, i.e. the number of the input of a
metering equipment having several inputs for the measurement of
energy of the same or different types (e.g. in data concentrators,
registration units). This enables data from different sources to be
identified
C Defines the abstract or physical data items related to the information
source concerned, e.g. active power, reactive power, apparent
power, cosφ, current or voltage.
D Defines types, or the result of the processing of physical quantities
according to various specific algorithms. The algorithms can deliver
energy and demand quantities as well as other physical quantities.
E Defines the further processing of measurement results to tariff
registers, according to the tariffs in use. For abstract data or for
measurement results for which tariffs are not relevant, this value
group can be used for further classification.
F Defines the storage of data according to different billing periods.
Where this is not relevant, this value group can be used for further
classification
To simplify the reading in the index field, individual parts of the OBIS code
can be omitted. The abstract or physical data C and type of data D must be
shown.
