Log Functions - Landis+Gyr ULTRACOLD T550 Technical Description

Log functions

12 Log functions
In the internal logbook, metrologically relevant events (errors, states, actions)
are stored in chronological order with their time of occurrence. The events ac-
quired are predefined. The data of the logbook cannot be deleted.
Each event is stored in a separate 4-level shift register; the overflows are
transferred to a 25-level circulating buffer. Therefore, 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 for
the past 18 months (without time stamp).
