2) to download the following information from the
dosimeter to computer:
- dosimeter ID (serial number);
- DER and DE alarm threshold values;
- DER and DE data logging interval;
- time delay to record the first event of DER and
DE history;
- DER and DE history (date, time, event, value)
according to preset data logging interval;

user-initiated recorded history;
- DER and DE history (date, time, event, value) at
alarm events;
3) to set the following parameters in the dosimeter
from the computer:
