2.4 Historical Data Function
DMC 3000 series dosimeters in G3 protocol have a historical data function which allows the following features:
Recording and dating of changes equal or greater than 1 µSv (0.1 mrem) in the cumulative doses (primary
and/or secondary) with the current Rate by intervals of 10 seconds, 1 minute, 10 minutes, 1 hour or 24 hours
depending on the dosimeter’s configuration.
Recording and dating of maximum rate between two dose records
Recording every second during 10s on rate alarm transition
Decreasing of the interval or record (10s instead of 1mn for exemple) when in Rate alarm for better accuracy
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.
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 (DMC 3000 alone or the same DMC 3000 with module) compared to G2
(DMC 2000 compatible) protocol (see note).

Calculated with an increment of dose every 10 histogram steps.
