1.3.  Integrated software 

The  integrated  software  controls  the  instrument  operations,  displays,  stores,  recalls  data, 
and allows the user to perform QC and calibration procedures and modify the user settings. 
The software version number can be read out from the Device Information or from the Self 
test submenu. 

 

Software  is  absolutely 

“Plug  and  Play”

,

 

it  can  read  out  and  detect  the  type  and  the  serial 

number of the instrument, therefore it will run the correct program for the hardware, without 
any  user  or  service  help.  Every 

 

software  version  is  upgradeable  (using  an  USB 

drive) by the latest program developed by DIATRON, and it can be downloaded from:
