Menu mode: Operation and setting
You can adjust the settings for six data loggers of the device in this menu. These data loggers (see
chapter „Menu 3: History/Loggers“ on p. 65) display the history of measured values:
1 Voltage line 1
2 Voltage line 2
3 Switch position of the transfer switching device
4 Load current I(3) in the TN system downstream of the transfer switching device
5 Insulation resistance
6 Load on the IT system in %

Risk of premature wear of the memory module.
The service life of the 500 memory locations of the EEPROM memory is limited to approx. 100 000
memory accesses. If one change to a measured value is saved every second, the end of the service life
of the EEPROM is reached after one year. If changes are saved every minute, the service life is increa-
sed to approx. 57 years. Select the settings in the "Datalogger -> "Modific." settings menu in a way
that frequent saving over longer periods of time can be avoided.
To protect the memory module, a minimum threshold of 10 A is incorporated in the data logger for
the load current downstream the transfer switching and monitoring device I(3) and a minimum
threshold of 20 % is incorporated in the data logger for the IT system. Values below this limit thres-
hold are only stored once. A new measured value will be stored in the memory only when this limit
threshold is exceeded.
Selecting a data logger:
1. Use the " " arrow button to go to the data logger settings. Press the " " button.
2. Use the arrow buttons to select one data logger (1, 2, …) or all data loggers (1…6). Press the
" " button to confirm your selection.
