elektor zener diode tester variant-46907023753548-has-digital-downloads or understanding their own coffee-roastingThe Elektor Zener Diode Tester is essentially a constant current source that can be switched in steps from 1 to 50 mA. It can be used to test Z diodes up to a maximum of 54 V. Thanks to a 60 V step up converter, the device can be powered by the usual 5 to 12 V. The principle of this tester is straightforward. A Z diode or other DUT (device under test, such as an LED) is biased by an adjustable current source. The voltage across the DUT can be measured
