Test Zeners, Avalanche Diodes, VDRs, TVSs, LED strings and much more (up to 50V!)

Key Features:

  • Measures breakdown voltage (0.00V to 50.00V) with a resolution as fine as 20mV.
  • Measures slope resistance (up to 1kΩ at 15mA with a 1Ω resolution).
  • Supports most Zeners, Avalanche diodes and reference diodes from 0V up to 50V.
  • Great for testing VDRs, TVSs and other types of voltage protection devices.
  • Selectable test currents: 2mA, 5mA, 10mA and 15mA.
  • Tiny duty cycle of test current to minimise heating of your component even when testing at 50V and 15mA.
  • Single Alkaline AAA battery (included).
  • 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.
  • Very comprehensive printed user guide.
  • 24 month warranty.
