Diode Measurements

This tutorial recommends tips and techniques for using a National Instruments digital multimter (DMM) to build the most accurate measurement system possible. In this tutorial, you learn how the NI 4070 can operate as both a 6½ digit digital multimeter and a fully isolated, high-voltage digitizer, capable of acquiring waveforms at sample rates up to 1.8 MS/s at ±300 V input. This section of the tutorial covers NI 4070 diode measurements.

For more information return to the Complete Digital Multimeter Measurement Tutorial.

The NI 4070 Digital Multimeter can excite a DUT with a constant current (amps) source and read the resulting voltage drop using a 10 V DC range. Diode mode is useful for testing p-n junctions, light-emitting diodes (LEDs) and zener diodes. The default current (amps) excitation is 1 mA and a voltage up to 4.5 V can be measured with this setting. You can also set the current (amps) source to 1 uA, 10 uA or 100 uA, in which case the voltage up to 10 V can be measured.
