In the internal logbook, metrologically relevant events (errors, states, actions) are
stored in chronological order with their time of occurrence. The acquired events are
predefined. Logbook data cannot be deleted.
Each event is stored in a separate 4-level shift register. The overflows are trans-
ferred to a 25-level circulating buffer. This way, at least the last 4 times can be
traced for each event.
In a monthly register, the error states are stored for the current month and the past
18 months (without time stamp).
