I've purchased a used Speedmaster densitometer (TRC-60CD) which came to me with no manual. Can someone offer a quick tutorial on calibration? I think I've got the zero and calibration, but wonder how to do the "null set". Thanks in advance for your help.

I have a manual for a TRC-60D that I have scanned for another poster. If you would like I can e-mail it to you. It probably would be close enough for your purposes or at least it can get you in the ballpark.
