Digit
A number representing a value from 0..9 in a decimal numbering system.
Energy values are often processed with 8 digits, i.e. resulting in a value
range from 0 to 99999999.
Energy register
Contains measured energy values in physical units, e.g. kWh, kvarh, ° C,
etc.
Energy value, cumulative
The amount of energy registered (or measured) by an input since its activa-
tion.
Energy value, current (increment)
The amount of energy registered (or measured) by an input or register
since the start of measurement (or the last reset).
Input
Receives signals from the outside into the data logger unit. These can be
pulses from meters, control signals (e.g. for maximum demand reset or
events). In the case of internal counter inputs, the values can also be nu-
meric values.
Jumping registration period
In this operational mode each registration period starts at the end of the
previous one. In difference to the rolling registration period, individual regis-
tration periods are strictly separated from each other.
Logic input, alarm input
Input that is monitored permanently. Changes of the input signal are stored
in memory.
Logic output, alarm output
Output, the status of which can be altered by the remote metering center.
Main memory module
Used for storage of measured and registered values and for data transmis-
sion to the remote metering central. Optionally data can be stored on a PC-
Card.
Maximum (demand)
The highest average demand value during a billing period. The data logger
not only stores the value as such, but also the timestamp of its occurrence.
Meter
Electro-mechanic or electronic device for the measurement of energy in an
electricity, gas or heat distribution network.
Output
Transmits signals of the data logger unit to the outside, e.g. pulses or rate
signals.
Power dip / Voltage dip
Event created after a very short failure of supply power (max. 200ms). In-
ternal power supply is bridged (secured) by means of integrated buffer ca-
pacitors. All data stored in the unit is retained. Data processing and the
internal real time clock are not affected.
