For Japanese made multi-tester how do you test a diode?

To test a diode using a Japanese-made multi-tester, first set the tester to the diode testing mode, indicated by a diode symbol. Connect the red probe to the anode and the black probe to the cathode; a forward-biased diode should show a low reading (typically 0.6 to 0.7 volts for silicon diodes). Then, reverse the probes; a good diode will show no reading or "OL" (over limit) in reverse bias. If the diode conducts in both directions or shows no conduction at all, it may be faulty.
