ATLAS ZEN - ZENER DIODE ANALYSER (0 - 50 V)

test Zener diodes, Avalanche diodes, VDRs, TVSs, LED strings and much more (up to 50 V)

measures breakdown voltage (0.00 V to 50.00 V) with a resolution as fine as 20 mV

measures slope resistance (up to 1 kO at 15 mA with a 1O resolution)

supports most Zeners, Avalanche diodes and reference diodes from 0 V up to 50 V

great for testing VDRs, TVSs and other types of voltage protection devices

selectable test currents: 2 mA, 5 mA, 10 mA, 15 mA

tiny duty cycle of test current to minimise heating of your component, even when testing at 50 V and 15 mA

single alkaline AAA battery (incl.)

long battery life and regulated test conditions even when the battery voltage is as low as 1.0 V

continuous measurement display (updated 3 times per second)

hold-function to hold displayed values even if component is removed

fitted gold plated crocodile (alligator) clips

comprehensive printed user guide available (English - German - Italian)
