==== Diode Mode ====
Diode mode is basically resistance mode, but sources a voltage on the positive probe and measures the forward voltage drop on the negative probe. For a healthy diode, this is somewhere in the ballpark of 0.6{{nbsp}}V{{--}}0.7{{nbsp}}V  but depends on the diode (see the specific datasheet for more information). By measuring the voltage drop, you can infer if the diode is healthy or not. once you do this, you should also swap the probes and do the measurement backwards to make sure there is not leaking in the reverse bias direction{{---}}this is a likely fault for diodes.
