Here is a handy zener diode tester which tests zener diodes with breakdown voltages extending up to 120 volts. The main advantage of this circuit is that it works with a voltage as low as 6V DC and ...

The circuit has been constructed to test and measure the voltage rating of zener diodes. To be able to test the voltage rating of a zener diode up to 50 VDC, a small transformer and a single 555 timer ...

The circuit presented here is compact and handy for measuring the voltage rating of a Zener diode instantly. To check a Zener diode, it is connected across a DC power supply with a suitable resistor ...

This Design Idea describes a versatile test circuit for zener diodes after yet another misread zener diode had infiltrated the ranks of 1N4148 diodes assembled on a pc board. As a bonus, the circuit ...

Abstract: In general, measuring electronic circuits can only use ordinary measuring tools or manually. But as technology develops, measuring electrical circuits does not only use manual tools but can ...

"How many volts above freezing is it?" A multimeter is the most common item of test equipment used by elec- tronic hobbyists. This is with good reason, considering how useful it is, but, of course, ...
