The segment test will be displayed first. After pressing the alternate button again the next data of the standard data readout list will be displayed for about 10s.
After the segment test will be displayed the standard data readout list of the meter can be read by the optical port. By using the exchangeable battery the readout feature is available even if the meter is not powered for longer than 4 years, depending on the number of readouts without main power.
The analog measured variables obtained are digitized in the ASIC and fed to a downstream digital signal processor, which uses them to compute the active or reactive powers plus the corresponding elsted, and forwards energy-proportional pulses to the tariff module. By using both digital multiplication and integration, significant advantages can be achieved in terms of measuring stability and flexibility.
The scanning frequency has been selected so as to ensure that the electrical energy contained in the harmonics is acquired with the specified class elstdr. Functional schematics of the meter. The reactive energy calculation is done by using a 90 0 epster shift between voltage and current and a elsetr multiplication of voltage and current according eq Theft resistant measurement always run positive The can be ordered with an optional theft resistant measurement that records negative energy flow as elstee energy flow.
This feature can be used to deter power theft or minimize the effects of improper meter wiring.
The following equation shows how total active power is calculated using theft-resistant measurement. Therefore, instrumentation can be used to investigate the meter service wiring, while the theft-resistant measurement guarantees that active energy is properly registered. Operation of the LCD energy direction indicators is modified by the theft-resistant measurement. With the theft-resistant option, the P arrow is not used.
The following figures shows how the energy direction indicators appear for negative active and reactive power when using standard measurement and theft-resistant measurement.

The back-lightened display will be activated for 2 minutes by pressing the alternate button. This feature will be available even if the meter is not connected to the main power. Operating display The definitions for import and export of energy have been agreed in terms of the load reference arrow system VZS.
For defining the transmission direction of active and reactive power, the specifications of the load reference arrow system likewise apply.

Display of activated tariff The tariffs T1 to T4 and M1 to M2 switched on at any one time are continuously displayed.
In addition, the following applies: Arrow to the right: Indicator for positive active power Arrow to the left: Indicator for negative active power Indicator for positive reactive power Indicator for negative reactive power The relevant symbols will flash when the meter is not programmed to measure this energy direction. The symbols for the measured variable involved have been switched off if the power is below the device’s start-up threshold.
Time particulars h, min, sec are separated by colons, date particulars year, month, day by the top dots of the colons. Alarm Indicator Alarm indicator: This indicator will be displayed if any error message of the meter occurs F.
The display control and the edit function for settable values are handled a20 means of “single-hand operator control” in conformity with the stipulations of the VDEW – Specification, i. Depiction of the different values on the display in the various display modes can be parameterized. The default status for the display is the operating display. A change from the operating display to the “Menu [A]-key” i.
From standard, second or load profile call mode you jump back into the operating display through the end-of-list identifier, or automatically if no control is operated within a defined time of 30 minutes, for example, or if the alternate button has been pressed for longer than 5 s.
The end of a list is designated in the display with the word “End” in the value range. Different operating modes for the display: The measured values involved are displayed in rolling mode, with the data relevant to billing being displayed for a configurable duration e. While a measured value is actually being displayed, then it will not be updated in the scroll mode. The display test mode is retained from approx.
During the display test mode, you can press the alternate button to switch to the “A-button menu” 6. Every time you press the alternate button briefly again, more menu slster as available will be displayed, e. For purposes of menu option selection, the alternate button must be held down for at least 2 s. If the time limit after the last touch on slster button has been reached this can be parameterized in a range from 1 min to 2 h or the alternate button has been kept depressed for not less than 5 s, the meter will automatically switch over to the scroll mode.
While a measured value is being displayed in this mode, eleter will be updated in the display once a second Standard mode Menu Option “Std-dAtA” The first value displayed in the call list is the Identifier and the content of the function error. Every time the alternate button is pressed again, further data will be displayed.
In order to call up data more quickly, existing preceding values can be skipped and the value following the preceding values can be displayed.

You do this by keeping the alternate button pressed down for longer than 2 s. If the time limit after the last touch on the button has been reached this can be parameterized in a range from 1 min to 2 h or the alternate button has been kept depressed for not less than 5 s, the meter will automatically switch over to the operating display.
The final value in the call list is the end-of-list identifier, which is designated in the display’s value range by the word “End” Second Standard mode Menu Option “Abl-dAtA” Furthermore the meter supports second standard data list Abl-dAtA. The handling of this list is the same as described in chapter The main difference between the 2 lists is that the Abl-dAtA list can be set without breaking the certification seal see chapter 7.
The final value in the call list is the end-of-list identifier, which is designated in the display’s value range by the word “End” Load profile values of the selected day Display of the day block selected begins by showing the oldest load profile values stored on this day the value stored at 0. Once all the period’s measured values have been displayed, they are followed by the data of the next available demand period. The last value in the call list is the lester identifier, which is designated in the display’s value range by the word “End” and which appears after the final load profile value of the day selected.
If the time limit after the last touch on the button has been reached this can be parameterized in a range from 1 min to 2 h or the alternate button has been kept depressed for not less than 5s, the meter will automatically switch over to the operating display. Disable times for a new demand reset by triggering a reset through interfaces optical, electrical t external control 0 t eltser t 1 t internal RTC of the meter 0 t 1 t 1 t 1 b The demand reset disable time can be configured to be cancelled by a power failure.
The number of the reset counting mechanism simultaneously serves as an auxiliary Identifier for the preceding values. Eleter that case the demand reset lockout time will not be started. The user elsetr the option for using an own identifier system but to follow the international standardization the OBIS Identifier system EN is recommended see appendix, chapter The standard data readout list contains all billing data.

All parameters of this list can be changed without breaking the certification seal. Only a password is required. X 6 Voltage phase L X. XX 6 Power factor phase L1 1. The “R5” and “W5” commands defined in conformity with EN are used for elstr purpose: In addition, the “R5” command can be used to read out individually all the registers contained in the readout list.
Depending on the meter parameterization involved, all or only some of the functions described below will be supported. Elsster it is possible to use a separate tariff source for the energy and the demand tariffs. R 4 of the 4 energy quadrants Combination of reactive energies, e. The total parameters provided for the block demand measurement are as follows: Duration of the maximum period: Power failure a Integration period is ended b Integration period is not ended Power recovery a A new integration period is started, and terminated synchronously with the device time b Depending on the duration of the interruption, either the integration period ongoing at the time of the power failure will be continued, or a new and perhaps shortened integration period will be begun.
The end of the integration period is always specified by the IP raster. The following integration period is terminated synchronously with the device time, and may be shortened if the resetting has not been synchronized so as to harmonize with the integration period raster. In comparison to the register reading, the Delta value represents the energy of the variable measured between two defined points in time.
In the meter, Delta values a2220 register readings can be displayed in parallel.
