EIB Delta-Meter
Electricity Meters
Displayed energy: The energy is displayed with a resolution of 0.1 kWh
(kvarh). In 'Alternative mode', the consumption value is displayed with an
additional decimal place after the point, e.g., 0.01 kWh (kvarh).
In the case of combination meters, the displayed consumption value alter-
nates approx. every 6 seconds between active and reactive power. The type
of value can be seen by the unit of measurement, i.e., kWh or kvarh.
In the case of tariff meters, the displayed consumption value also alternates
approx. every 6 seconds between each of the four tariffs and the sum of the
tariffs. Using the tariff indicators, it can be determined which tariff value is
currently being shown.
In the case of transformer rated meters, all displayed consumption values
and electrical measured variables are secondary measured values.
Note: The measurement of energy consumption takes place in all display
and programming modes. In the event of voltage failure or disconnection of
the device, the current measured consumption value is maintained, in spite
of the LCD display being inactive.
The EIB Delta-Meters have a light sensor (see 'General description'). This
has the same function as the 'SCROLL' button if a torch for example is shone
on the sensor. This enables the meter readings to be queried both in the
case of programmed devices and installed or sealed devices.
It is not possible to modify any settings with the light sensor.
The various read-out options of the EIB Delta-Meter are activated using a
menu-driven software. This menu is operated via two buttons:
'SET' button: It is used to activate the display menu [Menu mode] and the
sub-menus [3 Error ] and [4 Instr ].
'SCROLL' button: It has two different functions depending on the length of
the push button action:
When the 'SCROLL' button is pressed briefly, you can jump between the
individual items in the respective menu.
A long push button action (> 3s) switches from 'Normal mode' to
'Alternative mode' and from 'Alternative mode' to 'Instrument mode'. In all
other modes, a long push button action acts as a "Escape" function.
(The software jumps back one menu level).
Only one button may be pressed at a time.
The commands are only carried out once the button has been released.
If no buttons are pressed for two minutes during the programming, the
EIB Delta-Meter cancels the action and jumps back one menu level. This is
repeated until the meter is in 'Normal mode'.
