 I&rsquo;m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was? 
 
 There is another Community post with a similar error, and the problem was fixed by power-cycling. Here is the link for that: PFPD 5383 - Forum - Gas Chromatography - Agilent Community . 
 
 However, I would be curious to know what type of detector you are using.

Hello BESIK , 
 
 Thank you for your reply. If memory serves, ADC refers to the analog-to-digital circuit. So, if a power cycle didn't fix it, it is quite possible you have an electronic problem. 
 
 Unfortunately I do not have recommendations on how to address that yourself for safety reasons. I recommend you reach out to your local Agilent Team , so they can take a look at the electronics. 
 
 If you do manage to fix it, please reply with the solution so other Community users with similar issues benefit from it.
