- DE accumulation time indication;
- indication of counter of the left time of presence on the work place depending in
current measured DER and DE values;
- dosimeter number indication;
- audio alarm;
- setting DER and DE threshold values using buttons;
- reset DE using buttons.
2.4.7.4 Read-out from dosimeter to PC the following information (
РМ1621М,
P
М1621МА):
- dosimeter parameters;
- DER history and DE accumulation (date, time, event, value);
- DE value (DER) at the moment of set threshold exceeding, as well as time, date
and month when set thresholds were exceeded;
- values of set DE and DER thresholds;
- service information.
2.4.7.5 Record from PC into dosimeter the following information (
РМ1621М,
РМ1621МА):
- dosimeter parameters;
- DE and DER threshold values;
- recording interval of DER history and DE accumulation;
- current time and date for generating DE accumulation history;
- service information.
2.4.8 Search mode (
РМ1621М, РМ1621МА)
In the search mode the dosimeter enables functions of detection and localization of
gamma radiation sources (GRS). See figure 2.2 for the way to switch search mode on.
When first DER threshold level is exceeded (GRS are detected), audio, light and
vibro alarms rate will increase as the dosimeter is being moved closer to GRS.
When limiting frequency is reached, the dosimeter will emit continuous audio alarm.
At single pressing of LIGHT/SET button the frequency of audio, light and vibro alarms can
be decr
eased, that improves dosimeter’s detection power when it gets closer to GRS.
Another pressing the LIGHT/SET button resets the frequency of audio, light and
vibro alarms to initial state. When second DER threshold level is exceeded, dosimeter
emits frequent discontinuous audio, light and vibro alarms.
When
doing localization of GRS place the dosimeter so that dosimeter’s effective
center (attachment C, figure C.1) faces the tested object. Hold the dosimeter at the
distance of the tested object no more than 10 cm. Move the dosimeter alongside the
tested object no faster than 10 cm/s.
2.4.9 Indication mode of audio alarm state (
РМ1621М, PМ1621МА)
In the indication mode of audio alarm state (figure 2.2) the dosimeter enables
following functions:
- audio alarm on/off;
- indication when audio alarm is on/off;
- adjust audio alarm sound pressure (figure 2.5);
- indicate sound pressure level as analogous scale and digitally (from 1 to 4). Level
1 (one line) corresponds to minimum sound level, and level 4 (four lines) corresponds to
maximum sound level.
2.4.10 Indication mode of vibro alarm state (
РМ1621М, РМ1621МА)
In the indication mode of vibro alarm state (Figure 2.2) the dosimeter enables
following functions:
- vibro alarm on/off;
