Atlas ZEN50 Diode Tester

The Peak ZEN50 tests zeners, avalanche diodes, VDRs, TVS's and much more up to 50V! Great for testing VDRs, TVSs and other types of voltage protection devices. Features : Selectable test currents: 2mA, 5mA, 10mA and 15mA and it has a tiny duty cycle of test current to minimize heating of your component even when testing at 50mA and 15mA. It measures breakdown voltage (0.00V to 50.00V) with a resolution as fine as 20mV. It also measures slope resistance (up to 1kohm at 15mA with a 1ohm resolution). It uses a single Alkaline AAA battery (included) and has long battery life and regulated test conditions even when the battery voltage is as low as 1.0V. Test voltages are below levels described in the Low Voltage Directive 2006/95/EC. Continuous measurement display (updated 3 times per second). Measurement "hold" function to hold displayed values even if component is removed. Fitted gold plated crocodile (alligator) clips. Includes very comprehensive printed user guide.
