A time before which the meter is not read out can be entered in the input fields for date and
time. The first actual reading date then still depends on the selection of the "Interval"
parameter.
In the "Measurement type" pop-up menu, you can select whether the data, its average value
or the minimum or maximum value should be written to the database. The average and the
extreme values are determined by querying the measured value every minute.
In the pop-up menu "Primary counter" you can select whether the counter in question is a
primary counter. Primary counters are electronic meters that include transformer factors when
displaying the meter reading.
This pop-up menu is only available for MBus counters!
The input fields "Factor U" and "Factor I" are changed if a voltage or current transformer is
connected upstream of the counter. The measured value is multiplied by the factors before
being saved.
These input fields are only available for MBus meters and the electrical trade!
In the input field "OBIS code" a code matching the measured value can be entered. OBIS
indices are internationally standardized and are used in electronic data communication in the
energy market to uniquely identify measured values (energy quantities, meter readings) and
abstract data.
