[Test-Equipment] Hameg HM312-8 Service Manual

[Hamdi Esen]

Hello All,
Couple of weeks ago I bought a "HM312-8" dual trace oscilloscope. It requires some repair and calibration but I could find neither the service manual nor the schematics of this particular model. There are service manuals or schematics for every single model of HM312 series except "HM312-8". I would be very glad if someone send me the documents I need.
Thanks,
Hamdi Esen
