Hi!
I recently bought in ebay an used Ithaco NF 3921 lock-in amplifier that has no manuals. A search in internet for a manual was unsuccessful. I also e-mailed DL Instruments (which was formerly Ithaco) and NF Corporation in Japan (the manufacturer, according to the label on the back of the instrument). I got no answer from them.
Tried also other sources like ArtekManuals and Manuals Plus, but no luck there either.
I'll be very grateful if someone can tell me where I can download or buy a copy of the user and/or service manual for this lock-in amplifier. A digital copy (in pdf. djvu, jpg, etc.) would be OK.
Thanks in advance for any help.
