Hi,

 

We are using SCXI1104/SCXI1102C/SCXI 1125,  Can we use the neutral as a reference of our measures, or this will cause damages in the SCXI Module.

PS: Our DUT (device under test) is supplyed with  230VAC /50Hz and it has only one mass which is connected to neutral.

 

 

An isolation between the SCXI and the DUT is it necessary

 

thank you for any help

 

Please it is urgent

Hi Sadok,

 

If your DUT has the potential to connect 230 VAC to the SCXI, I would recommend that you do use proper isolation. The SCXI 1125 has 300V channel to earth and channel to channel isolation. So that should be sufficient.
