2 USE OF THE DOSIMETER
2.1 General guidelines
When purchasing the dosimeter it is necessary to check the delivery kit (chapter
1.2.1) and the proper operation of the instrument in all the operation modes (chapter 2.4).
Protect the instrument from shocks and mechanical damages. Avoid exposing the
dosimeter to hostile environments, organic solvents and open fire.
2.2 Safety instructions
During the dosimeter adjustment, checking, repair, maintenance and verification, if
the radioactive sources are used, the regulations for work with radioactive materials and
other radiation sources, as well as Standards of radiation safety should be followed.
2.3 Preparation for use
2.3.1 It is necessary to study all sections of the present operating manual before
using the dosimeter.
2.3.2 Unpack the dosimeter.
2.3.3 Switching on:
-
unscrew the battery compartment’s cover using the screwdriver;
-
insert the battery, observing the polarity (battery’s electrode marked with “+”
should be directed inside the dosimeter);
-
fix the battery compartment’s cover in its place.
Right after inserting the battery the dosimeter performs LCD testing (all the
segments and graphic symbols should be displayed for about 2 s and then disappear),
then the dosimeter should enter the measurement mode. One minute after inserting the
battery the dosimeter is ready for use.
2.3.4 Place and fix the dosimeter, detector outwards, on a breast pocket of overalls
or inside it.
Attention! If the dosimeter is expected to be used under conditions when the
dose rate value is higher than 0.1 mSv/h, it is recommended to insert a new battery.
2.4 Use of the dosimeter
2.4.1 Dosimeter operation modes
- photon radiation DER measurement mode;
- photon radiation DE measurement mode;
-
dosimeter’s number indication mode (“blind dosimeter”);
- mode of data transmission to PC;
- search mode (for
РМ1621М and РМ1621МА);
- mode of audio alarm state indication;
-
mode of vibro alarm state indication (for РМ1621М, РМ1621МА)
- partial or critical battery discharge indication mode;
- settings mode;
- audible alarm mode at the exceeding of the preset DE or DER thresholds, as well
as
vibro and light alarm mode for РМ1621М and РМ1621МА additionally.
The dosimeter’s non-volatile memory ensures storage of the following values when
replacing the battery for the moment of the battery’s removal:
- accumulated dose (DE);
- DE accumulation time;
- DE and DER accumulation history;
- preset DER and DE thresholds values.
