My name is Sue and I am a Customer Advocate with Thermo Fisher Scientific. You can access user manuals at www.thermoscientific.com/elabservice for those within North America, and www.thermo.com/elabservice for those outside of North America.

Just do a quick search for your model (Sorvall RC3BP), and the PDF files can be viewed or downloaded from there. I was able to find specific instructions on Accumulated Centrifugal Effect settings by opening the user manual and searching for 'ACE'.

I can send you a copy of the manual, too, if needed. Just contact me at the email address below. I hope this helps!
