The dosimeter displays current time in hours (
24), minutes (60) and allows for setting and correction of
current time in hours (24), minutes (60), as well as day, month and year.
Dosimeter automatically, in preset data logging intervals, re
cords into its permanent memory and stores
up to 7500 events (1 to 7500) of DER and DE measurement history. Depending on the type following events
have to be stored in the instrument nonvolatile memory:
- current DER and DE value;
- current time (year, month, day, hour, minute);
- DER and DE value in case of alarm event;
- instrument status changes ("switching on", " switching off", etc.).
The dosimeter provides the foll

to enable or disable setting of DER and DE
alarm thresholds, DER and DE history parameters
from the front panel using control buttons;
