XS user manual v0.55  - 148 - 
Uses cases 
 
  Test piece (DUT) correctly connected. 
 
 
Reminder: 
 
   : Voltage re-reading lead. 
 
   : High voltage generator HV lead. 
 
   : Voltage re-reading return lead. 
 
   : Return lead (GND) from the high voltage generator. 
 
 
When the test piece is properly connected, points 1 and 2 are connected together via connection zone A. 
The same applies to points 3 and 4 connected together via connection zone B. In this  case the high 
voltage  is  returned  to  the  voltage  shunt  and  the  other  terminal  is  brought  to  0V  (GND).  Relay  Re1 
contacts are open.  
Hence the voltage generated can be re-read across the voltage shunt.
