22 In the mode of data transmission to PC
the dosimeter provides the following
functions:
1) permission or prohibition (switch
ON/OFF) of the following operating
modes (parameters) of the dosimeter:
- DER indication;
- indication of current time or indication
of DER averaging time and
DER coefficient of variation;
- DE indication;
- indication of DE accumulation time;
- indication of the dosimeter’s number;
- alarm clock;
- timer;
- stop-watch:
-clock-calendar;
- audible alarm;
- preset of the DE and DER threshold
levels using the buttons;
- DE reset using the buttons.
2) read-out of the following information
from the dosimeter to PC:
- dosimeter’s parameters;
- DER history and DE accumulation
(date, time, event, value);
- DE (DER) values at the moment of
exceeding the preset thresholds as well
as time, date and month of exceeding
the preset thresholds;
- values of the preset DE and DER
thresholds;
3) recording of the following information
from PC to dosimeter:
- dosimeter’s parameters;
- values of DE and DER thresholds;
- interval of DER history and DE
accumulation recording;
- current time and date for forming DE
accumulation history;
