7 Operating the meter
7.1 Operation modes
7.1.1 Parameter status (PAR-Status)
The PAR-Status is used for configuration of the meter at the factory. For activation
of this mode press the PAR-Status button. This button is found on the meters main
PC-Board and is protected by a seal.
7.1.2 Test mode
In the test mode the resolution of the energy register is 100 times higher than the
resolution in the standard operation mode. This also applies for the readout table.
The test mode is also addressed via the write command 1.58.T(N) for active energy
and 3.58.T(N) for reactive energy.
„N“ = 1 means activate, „N“ = 0 means deactivate. „T“ stands for the number of the tariff
which is activated with the command.
Activation of the test mode is shown by the simultaneous flashing of the star symbol
and the exclamation mark in the display (see page 21). After 24 hours uninterrupted
operation the test mode is automatically deactivated.
7.1.3 Standard operation mode
When the meter is in normal operation then it is always in the standard operation mode.
7.1.3.1 Standard display
After meter installation and running through the display tests the meter is in the standard
display. With a multi tariff design, the energy value and the designation of the active tariff
are shown in the display.
With a two tariff meter with static display the energy value for high tariff is displayed in
the value area and the energy value for low tariff in the OBIS code area. Thereby the
digitness of the high tariff value is reduced from 8 to 7.
From every condition the display returns back to the standard display providing that the
display was not operated within the configured delay period (5 to 30 minutes).
7.1.3.2 Error status display
During operation of the meter a continual check takes place of the register data, the code
and also the checksum. If during the check an error is recognised then an error code is
shown in the display.
