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 G

В 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;
