I see three files with schematics, probably all from the same source material, on
BAMA:
Sencore_LC102_Auto_Z_meter_Operator_Manual.pdf
Sencore_LC102_Schematics_112_pages.pdf
These contain what appears to be the same schematics, with some pages rotated relative to each other.
Sencore_LC102_Schematics.zip: This file contains the stitched schematics with some of the missing parts filled in, and the rest as white. The resolution isn't great, but looks mostly legible.
