2.3 Historical Data Function
DMC 3000 series dosimeters have a historical data function which allows the following features:
Recording and storage of changes greater than 1 µSv (0.1 mrem) in the cumulative Hp(10) dose by
intervals of 10 seconds, 1 minute, 10 minutes, 1 hour or 24 hours depending on the dosimeter’s configuration.
Recording and dating of significant events such as:
alarms and warnings
acknowledgment of warnings
assignment of identifier, task and RWP codes
change in operating mode (
Pause
and
Run
)
dosimeter fault
parameter changes
In order to date accurately all the data, the DMC 3000 is equipped with a Real Time Clock to keep the clock
time. In satellite mode, this RTC could be set during configuration with a reader during entry.
If the DMC 3000 is in G3 protocol, all the events and dose increments are dated in date format (DD/MM/YYYY
and HH:MM:SS) and the time size of recording is doubled (see Note) compared to G2 (DMC 2000 compatible)
protocol where the number of histogram's steps is limited to 3800 (see §6.9 for details).
