4.1.1 

Function modules 

The base station contains the battery supply, the high voltage generator and regulator as well as several safety features. 
 

 

 
The  pistol  houses  the  interchangeable  pulse network, high voltage  relay,  the exchangeable  discharge  tip, measuring  elec-
tronics and the touch sensitive input / display panel. 
 

4.1.2 

Block diagram  

The various function units are shown in the block diagram:  

Block diagram of the base station: 
 

 

 
The microprocessor controls and monitors all the simulator functions:  

•

 

Touch-panel entries are checked for plausibility. Unacceptable entries are rejected and an acoustic warning notifies 
the user of the error.  

•

 

Values entered are clearly shown on the large display screen. Further information shows the operating status and 
the counter settings.  

•

 

The battery charge state is continuously monitored. The display warns if there is a tendency towards low voltage. 
The instrument’s functions are inhibited once the battery voltage is insufficient to guarantee the pulse parameters.  

•

 

The actual tip is detected and the actual discharge mode will be shown.
