Atlas Zen Zener Diode Analyser

The Atlas Zen Zener Diode Analyser is a sophisticated and compact instrument designed for precise in-circuit testing and identification of a wide range of semiconductor components. It enables reliable measurement of Zener and avalanche diodes, VDRs (Voltage Dependent Resistors), TVSs (Transient Voltage Suppressors), and LED strings, handling voltages up to 50V. Its primary function is to determine the breakdown voltage with an impressive resolution of 20mV, a critical specification for component verification and circuit troubleshooting.

Beyond voltage, the analyser measures slope resistance up to 1kΩ at a test current of 15mA. It offers user-selectable test currents of 2mA, 5mA, 10mA, or 15mA, providing flexibility for different component types. A smart duty cycle is employed to minimise component heating during testing, preserving the integrity of sensitive parts. The device ensures regulated test conditions and maintains long battery life, functioning accurately even as the battery voltage drops.

Engineered for safety and compliance, all test voltages operate below the thresholds defined in the Low Voltage Directive 2006/95/EC. The analyser provides continuous real-time measurement, updating readings three times per second for dynamic testing. A useful 'hold' function retains the last measurement on the display even after the component is removed, allowing for easy recording of values.

For dependable connectivity, the unit is fitted with gold-plated crocodile clips, ensuring a low-resistance and corrosion-resistant connection. Power is supplied by a single included AAA alkaline battery, making the tool fully portable for bench or field use. The analyser is supplied complete with a comprehensive user guide, facilitating immediate operation for both professionals and enthusiasts engaged in electronics repair, design, and quality control.
