Leader LEM-73A Manual

[cahlucas]

I recently bought a second-hand Leader LEM-73A electronic multimeter, and I miss the manual, especially the schematic. Attached is a photo of the device. I would like to know if anyone could help me with this. If possible, please in PDF format.

This is the manual of the LEM-75A, I think in Spanish. I also discovered this manual on the internet, what concerns me is really the manual for the LEM-73A. The difference is that the LEM-73A has the ability to perform Ohm measurements with high and low voltage, and the LEM-75A does not. You can measure PN transitions with the high voltage (1.5 V), but not with the low voltage (88 mV). This opens up the possibility of measuring resistances without opening PN junctions. So I'm still looking for a manual for the LEM-73A.
