Menu HISTORY INFO
99 events with date and time stamp can be stored in the memory database.
The database is designed as a ring memory, i.e. the eldest entry is overwritten.
Data is written into a non-volatile memory and therefore is protected against
voltage failure.
Data can be queried via the "HISTORY INFO" menu as follows: to change the
data record number use the Up/Down buttons, to toggle between the data re-
cord number and the menu item for clearing the history memory
("Clear all:on") use the Enter button, and to leave the menu item use the "ESC"
button.
In the standard mode, a new entry in the history memory is identified by an
"H". To delete the "H" you have to open the HISTORY INFO menu item first.
To store the events with the actual date and time stamp, you
need to set the real-time clock in the ISO ADVANCED menu first.
