automatically in approximately 60 s, the repeated audible signal will sound in
approximately 4 min.
2.4.6 The dosimeter’s number indication mode
In the dosimeter’s number indication mode the following items are indicated on the
LCD:
- the dosimeter’s number on a display (2);
- year (4) and month (3) of production.
2.4.7 Mode of data transmission to PC
2.4.7.1 The dosimeter allows storing and transmitting to PC a history (further –
"history") of DE, DER accumulation, events of exceeding the preset DE and DER
threshold values, event of DE reset trough IR communication channel using the buttons.
Selection of the events to be stored in the history, frequency of these recordings is
performed under a special program. History data are inaccessible without IR adapter
(internal or external).
The dosimeter performs data transmission to PC under the user software supplied
on CD through the adapter of IR communication channel over the communications
protocol compatible with IrDA interface.
System requirements to a computer:
- A PC not lower than Pentium III;
- 1 GВ free HDD space;
- printer and unit for operation with IrDA protocol for the exchange of information
with the Dosimeters are necessary for comfort program running;
- The program runs under OS Windows 2000/XP/VISTA, Windows 7.
2.4.7.2 For using the dosimeter in the mode of data transmission to PC it is
necessary to:
- read the user software supplied on CD;
- connect the adapter of IR communication channel to a PC COM port (using the
adapter built in a PC shall be permitted);
- install the unit of IrDA communication in the system and switch on the IR
connection in the mode of searching external IR connection devices;
- install the user software supplied on CD to PC;
- orient the dosimeter and adapter of IR communication channel of the PC by
placing the dosimeter at a distance of 10-20 cm from the adapter of IR channel;
- choose the mode of data transmission to PC using the MODE button (figure 2.1);
- press and release the LIGHT/SET button for PC link startup through IR channel;
- perform readout of the dosimeter's information, following the program's
instructions.
2.4.7.3 Allow or prohibit operation modes (parameters) of dosimeter (РМ1621М,
РМ1621МА):
- DER measurement;
- DER coefficient variations indication;
- indication of DER averaging time;
- DE measurement;
