[volt-nuts] Looking for Advantest (ADCMT) User Manual/Schematics

[Sven Schnelle]

Hi List,

recently i acquired an old Advantest R6581 Multimeter. When i received 
the unit, it didn't show anything on the display. It turned out that the 
backup battery leaked, and some traces on the PCB where interrupted. 
After fixing them,
it showed the R6581 welcome banner, and after that "RUNNING SELF TEST". 
Now the self test fails with 'Internal Zero error'.

I'm not sure whether that's because it lost all of its calibration data, 
or if that's a real error on the Analog PCB. Does anyone on this list 
have some experience with those units, or a User Manual/Schematic?

It would be really sad to have such a nice 8 1/2 digit multimeter in a 
non-working state...

Regards
Sven
