Detection of capacitive samples 

 
Before starting a test, it is possible to detect whether the sample is properly connected to the unit or not. 
This is possible provided that the sample to test has a capacitive value of at least 10nF. If the detection 
is activated, a pulse of 100V magnitude and of 1s duration is generated, right before the hipot test starts. 
The  capacity  value  is  deduced  from  the  current  measured  during  this  pulse.  If  the  capacity  value 
deduced is high enough, the sample is considered detected and the test continues. Otherwise, the test is 
stopped, and the hipot voltage is not generated.      
 
By default, the detection threshold is set to 10nF. When the EXPERT mode is activated, it is possible to 
configure this detection threshold between 5nF and 10nF by 1nF steps and between 10nF and 1000nF 
by 10nF steps. 
 

  Precision on the detection threshold : ±40% 

 
Ex: To detect samples of at least 10nF capacitive value, a threshold of at least 10nF(1-40%)=5nF should 
be  set  to  ensure  that  the  absence/presence  of  the  sample  will  be  detected  every  time.  Likewise,  a 
detection  threshold  of  10nF  ensures  the  detection  of  absence/presence  of  samples  with  capacitive 
values of at least 10nF/(60%) = 17nF.
