Sigh. Doesn't ANYONE ever go to the OEM website for help anymore?

The first and most obvious place to look for the manual is from the
manufacturer.
Download the manual from Agilent's web site

Hello Renaud,

As you already know, the manual from Agilent does not include the
schematics. According to my manual (which has the schematics), this error
code is:

The output amplifier is unable to supply a negative offset. Possible
faults:
Output amplifier A1
Offset DAC A2: U24, U25, U26, U17
Offset latches A2: U21, U22, U23, U43

I've fixed a few of these with this code, and IIRC the problem was an easy
one to solve - the -24VDC supply had a problem. If yours is bad, check the
following:
1. 2200uF capacitor C4
2. CR2 bridge rectifier
3. U4 voltage regulator
4. Picofuse located in the -24VDC feed.

I'm currently posting the complete service manual to
alt.binaries.schematics.electronic, it should be there by the time you
look. Good luck!

Please consider uploading it to BAMA also -- a much more useful place
for posterity.
