Measuring diodes

The diode measurement function applies a small DC voltage to the junction under test and displays its forward drop (typically 0.2-0.7 V for silicon diodes). The instrument thus quickly verifies the correct polarity, the PN state of the transition and detects possible short circuits or interruptions. When correctly connected, the LED indication of the pass-through is lit; in the opposite direction, the multimeter displays a high or infinite value.
