3.2.23 The dosimeter features “Clock” and “Alarm clock” operating
modes.
3.2.23.1 The alarm clock rings during one minute or until a button is
pressed.
3.2.24 The dosimeter has a threshold alarm system with two
independent threshold levels:
- DER;
- DE.
3.2.24.1 The values of DER threshold levels are programmed within the
range from 0 to 999 999 μSv/h with a discreteness of 0.01 μSv/h.
3.2.24.2 The values of DE threshold levels are programmed within the
range from 0 to 9999 mSv with a discreteness of 0.001 mSv.
3.2.24.3 The programmed values of threshold levels are saved in the
nonvolatile memory of the dosimeter and are not changed when the
dosimeter is switched on/off or the storage battery is replaced.
