6.3 Menu HISTORY INFO
99 events with date and time stamp can be stored in the memory database. The data-
base 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 record 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". The "H"
will only be deleted when the HISTORY INFO menu item is called up.
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. (refer to Page 45).
