Digital multimeters can test diodes using one of two methods: Diode Test mode: almost always the best approach. Resistance mode: typically used only if a multimeter is not equipped with a Diode Test mode.
When testing a resistor, the multimeter is passing a known amount of electrical current through the resistor and then measuring the amount of current that With that said, multimeters are designed to use scales. These scales determine how much current the multimeter will use during the test.
