I have a good quality printed copy of the CF-350 user manual. If someone has this analyzer but no manual, I would be happy to send this for the cost of postage. And maybe a cup of coffee. There is a lot to the manual. Looks like about 1.5" of paper, printed double-sided. I used to have one of these analyzers and found the manual to be extremely helpful in learning how to use it. But sadly I didn't have the service manual, so when the analyzer stopped working that was the end.
