Dear Cassio Alvarenga ,

please have a look at a copy (from 2002) of that manual:

https://imageserv11.team-logic.com/mediaLibrary/2033/Veeco_VIC_MS17AB_Leak_Detector_Manual.pdf

But I fear, that the 'electrical' information(s) you want, are not included there...

There is only a diagram about the vacuum system in Fig. 4.

You may ask the manufacturer ... (if he still exists)

Best regards

G.M.

Thank you Gerhard Martens ,but I already found this link on internet, this is only the first 9 pages.

I already contacted the manufacture, with no success, they only want to sell a new one...
