I'm looking for the Service manual for the H04 version of the HP 3460B.? H04 adds an additional digit to the display and has improved accuracy.

I have some info for the 3460A-H04 but not the B

?

Looks like specs / service information.?

It is part of a set of fiches that cover 3460A specials and is a little randomly organized and poorly scanned

Seems like there are multiple copies including parts lists, board layouts and schematics

?

Would this be of help?

?

I'll keep looking for the B version

?

The H04 manual for the 3460A is just the normal manual with some change sheets for the H04 modifications, if there is a 3460B H04 version you should be able to use the 3460B manual at the web archive, I could probably dig out the 3460A H04 change sheets to scan.

ArtekManuals have at least one version of the 3460A manual, but not the H04 option.

?

I also have some info on the chopper oscillator modification, used in the later 3459/60 voltmeters, which is attached.
