  • 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 and 15 mA.
  • Also ideal for measuring the forward voltage of diodes (including HV/EHT diodes that can have very high forward voltage drops).
  • Tiny duty cycle of test current to minimise heating of your component even when testing at 50 V and 15 mA.
  • Measures breakdown voltage (0.00 V to 50.00 V) with a resolution as fine as 20 mV.
  • Measures slope resistance (up to 1 kΩ at 15 mA with a 1 Ω resolution).
  • Single Alkaline AAA battery (included).
  • Long battery life and regulated test conditions even when the battery voltage is as low as 1.0 V.
  • 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.

What's included?

  • ZEN50 instrument.
  • Comprehensive printed user guide.
  • AAA Alkaline Battery.
  • Fitted premium gold plated croc clips.
