Schematic for tenma 72-540 or sansei 6100 signal tracer

hello
found your message board looking for schematic and possible a user manual.
I have a tenma 72 -540 signal tracer/injector,looks very similar to sansei 6100.
downloaded the sansei schematic,,looking to see if perhaps there is a English translation version.
if available please let me know.
thanks
John Watermeier
