I built an OCD 2 and measured the diodes using the diode test on my multimeter. From memory forward voltage was 0.6v, which is a bit different to a typical silicon diode. If the circuit around was designed to match the different forward voltage i am not sure it would sound much differen...
We call this minimum voltage threshold in the forward direction the diode’s forward voltage drop. The reason for this is becausea circuit loses or drops this voltageat the diode. We can examine this by using a multimeter and measuring across the leads of a diode while it is in forward-bi...
Solving this problem using legacy tools can be time-consuming: it means setting up a DC power source and resistor to test each LED individually. Fortunately, the Fluke 87V Industrial Multimeter has a built-in diode test mode, so that technicians can identify the defective LED and fix the prob...
Fortunately, tools like digital multimeters make it easy to measure diode health and determine when it’s time to replace diodes. This allows technicians to keep circuits in good running order, powering the electrical systems we all rely on. ...
and use a multimeter to monitor the voltage regulator at the same time. The voltage value across the diode (the voltage range of the multimeter should depend on the stable voltage value). When the multimeter's indicated voltage indication is stable, this voltage value is the stable voltage val...

Can you explain a bit on what you mean by "isolating" transformer? Before connecting anything to the Arduino, I shall check with my multimeter first. Is that what you mean by "isolating" transformer? My immediate reaction to this question and the way you phrase it, is to tell you...
Set your multimeter to the highest current setting, usually 10 or 20 Amps Attach the output leads of the PST-DCCP (black and yellow leads) to the ammeter Note: this shorts the PST-DCCP, but it is OK, since the PST-DCCP can handle a short circuit. Don't try this with other power ...
Tunnel diode transmitter is adjusted with external multimeter to determine the diode's negative-resistance region. Some tunnel diodes will not "take off" as easily as other types. Depending on your diode, you may find it necessary to touch the cathode terminal at some point between the d...
